The NFL Offense: What is it? Why does every team use it? And how does it differ from college?

I am frequently asked why I don't more often discuss NFL offenses. Haven't many of these college gurus been chewed up by the NFL? Didn't the NFL "prove" that the run & shoot can't work? Isn't the NFL football's highest level, and doesn't it therefore have the most money and resources, the best people, and shouldn't the result then be that NFL football is the most strategically interesting?

Yes and no. There's several reasons why I devote less space here to what NFL teams do than for college teams. Far and away the most significant reason though, is that, somewhat counterintuitively, NFL offenses are surprisingly bland and homogenized. Not entirely, but as a rule of thumb, 80% of what NFL teams do on offense (or defense, really too) is extremely straightforward to the point where every team runs the same stuff. And the list is not that long. In an appendix at the bottom, I have cataloged basically the entire set. Most notably, the whole NFL's entire run game amounts to about four or five plays: the inside zone (also known as the "tight zone"), the outside zone (also known as the "stretch play" or the "wide zone"), power, counter, and some kind of draw, particularly the lead draw. No matter what cosmetic deceptions you see when you watch an NFL game (and remember, these cosmetics are supposed to be good enough to fool the opposing coaches who have studied film all week), you're seeing the same plays over, and over, and over again. There is some admitted monotony to this. Indeed, after today, having sketched out a great deal of this 80% of the NFL's offense, there won't be much need for me to come back to what a specific NFL teams do.

But what of all those stories of Jon Gruden or Andy Reid getting only 45 minutes of sleep a night (and of course sleeping in their offices), and all the film study, 500 page NFL playbooks, and lengthy gameplans buttressed by exhaustive statistical analyses. This is the other 20%, which often is interesting. But it is interesting in a very specific way -- within the framework of the basic, repetitive concepts that compose the other 80%. NFL coaches are understandably obsessed with "matchups," a word favored by every football talking head. The coaches spend an incredible amount of time focused on how to get this receiver to go against that safety, this blitzing linebacker against that tight-end, or this pulling tackle against that defensive end. It's an evolving, repetitive, circular, intensive battle.

Yet is of limited ongoing or generalizable significance. Let's say an NFL coach wants to run the counter trey, which is a run play where one lineman pulls and traps (i.e. blocks from the inside out), and another blocker (either lineman or tight-end) leads (i.e. goes up into the crease and looks to hit a linebacker). He might alter the assignments, or use a particular motion or shift or formation, because he wants the kick-out block to go against a certain guy and the lead against another. And, if successful, you, as spectator, probably won't notice what he did: the coach wasn't looking for a pancake block, just "success," which might be as simple as the blocker's getting in the way enough that the runner could get four yards. This "matchup" isn't always as dramatic as you might think. This does not demean its importance, but, from my perspective, does not always lend itself to lengthy, repeated examples.

Moreover, getting into this minutiae requires a great deal of digging and backstory. What have these teams done in the past? Who is injured this week? What is the history between the opposing coaches? I have discussed some of this type of thing before, for example, here. But again, this great complexity ironically flows from a rather bland and homogenous set. The NFL appears populated by eternal, diligent tinkerers rather than broad thinkers.

Television's role

There's a final reason, however, that I don't routinely get into detail with NFL offenses: I'm not convinced the NFL wants anyone to. Whether a marketing decision or one to placate paranoid franchises --word is guys like Mangini are exceptionally controlling of the flow of info, including requiring people to burn and destroy film or handouts -- NFL films does not actually make this footage available, and most of what it shows are such extreme close-ups that it is impenetrable from a strategy perspective. Part of the theory is undoubtedly the desire to overcome the fact that it is marketing a sport where all the players wear masks, something the NBA and golf and most other sports don't have to deal with.

Unfortunately, the result is that it's impossible to get a sense of what is going on during a play: the quarterback releases the ball, the ball floats magically in the air, and the receiver appears like an apparition out of nowhere to catch it. And the practical questions remain. What coverage were they in? What route did the receiver run? What complementary routes did the other receiver run? Who rushed the quarterback? Who picked up those rushers? It's impossible to tell. Take the clip below of the 49ers's dramatic, waning minutes victory over the Bengals in Super Bowl XXIII.



There's a couple of times where you can get a sense of a route or two, but there's not one play where I could (a) diagram the play in its entirety, i.e. all the receivers, or (b) more importantly, tell you what exactly the defense was doing, particularly the secondary. On the big pass to Jerry Rice over the middle, it's clear he ran a dig route, but it's not clear why he was so open. And then the voice-over goes so far as to tell you the actual name of the game winning touchdown play, yet could you tell me what any of the receivers besides John Taylor did on the play? Wouldn't the coverage on Jerry Rice, who would up MVP of the game, have been relevant as to why Taylor was so open? (Both Bill Walsh and Joe Montana later diagrammed the play in their books; there was actually a problem with the playcall as meshing with the formation.)

Fine, that's NFL Films. But what about watching the game on television? Yes, you get some replays, but generally it is not much better. You're lucky if you see the linebackers. Homer Smith once gave advice to people who watch football on television: Don't watch the ball, watch the defense -- you'll never miss where the ball winds up going. Yet he admits that with modern angles this advice is often impracticable. Ironically, too, the NFL, with more money (and likely its intent to market personalities) affixes its camera angles tighter than do college broadcasts My sense is that many college games can only afford a couple of cameras, so they pick a couple that can get a flavor for more of the field. The NFL instead overdoes it.

Why so simple?

That 80% of every NFL teams' offense consists of the same bunch of plays run over and over, combined with the inadequate broadcast techniques that robs the viewer of the ability to decipher the minute game-within-a-game adjustments that are going on, helps explain why it is not always worth it for me to discuss with great specificity what each NFL team does. But that still doesn't answer why NFL offenses are like this. (Defenses have the same issue of 80/20 blandness, though they will sometimes give incredibly exotic looks solely due to the freakish nature of some of the players. NFL cornerbacks can constantly play "press-bail" -- meaning they can show bump and run and yet be able to "bail" and play deep if necessary -- because they are so athletic, and I've seen guys like Ravens safety Ed Reed do miraculous things like line up directly on the line of scrimmage over a tight-end and then at the snap retreat and play deep half-field safety on the opposite side of the field. Other than the kind of stuff that you can only do if you've won the DNA lottery, NFL defenses all tend to be the same as well.)

Theories abound to explain the phenomena. Ones often trotted out: NFL coaches are closed minded; they don't understand the option/spread/wishbone/etc; the speed of the game is much greater than it is college; it's all some sort of conspiracy; and, finally, we have it all backwards, and this NFL-homogenity is actually somehow better, we're just missing it.

These can be dealt with in short order. The NFL has the most money and pressure at stake, and coaches have little job security. There is no reason for them to be so closed minded. And they certainly do understand the option. Many have coached at other levels before, and, though they might not be experts, it doesn't take long to explain how the option and the spread work and why they have been effective. The conspiracy stuff is bunk, and I think it can't be argued that the NFL is not homogeneous or monotonous, and, in theory at least, more diversity would be better, no? Most of the NFL offense defenders argue that the players make it worthwhile to do this, or the passing game is what makes it all necessary, or there is some hidden meaning we're all missing. (This argument is more common than might be initially guessed, and usually takes the following form: "The NFL is better because all that stuff is just a bunch of gimmicks," with "gimmick" being the derogative catch-all term for anything that breaks out of the 80% mold delineated in full below. As described below, one unfortunate plank of this argument is the reliance on the idea of "ideal" football.)

The speed argument is more difficult to discard, though I think for now we can ignore it. On the one hand, the idea that the defense is faster suddenly dooms all these schemes common to college seems bizarre considering that the offensive guys are (or should be?) faster too. Thus, relatively, there is no speed advantage. On the other hand, if NFL players are all both bigger and faster, then in practical terms the field itself has shrunk, even if the players are relatively the same. Yet on the other, other, hand, with more straight ahead speed and better quarterbacking, teams can better stretch the field vertically. On the whole, unless someone wants to do some real studies, I find this rather inconclusive.

There are three arguments that I think do help explain the NFL 80/20 blandness. Note however that not included in this list is the meme popular among the NFL itself (and those announcers!) that what they do is simply "better." The problem with this idea is that "better" begs too many questions: Better than what? Better how? Better as a professional offense with professional players, or better for high school players too? What is better considering that there is time to integrate any concept you want into your playbook? Isn't the "better" thing then just the more time and resources you have? So I leave this aside.

The three are:
  • Coaching incest. The NFL fraternity is too incestuous, and thus they don't get out of their comfort zone enough and don't seriously engage with what is going on elsewhere.

  • Lack of incentive to experiment.Related to above, but the idea is that, post free-agency, there is little reason for NFL coaches to "think outside the box," and when they do and fail, they will be ridiculed and fired. For example, Marv Levy famously went to the Wing-T offense with the Kansas City Chiefs in the late 70s and early 80s, and was promptly fired.)

  • The quarterback obsession. The money and necessity involved with NFL quarterbacks has so come to dominate the thinking and strategy behind the sport that it hampers both experimentation but literally what they have time to do. If you ask an NFL coach what he spends his time on, or why they don't use more run plays, and he will likely tell you that they spend all their time on pass protection and protection schemes, and this cuts down on what else they can do.
I think all three of those ideas have some merit. The incest idea sounds a little odd, but then you remember that the vaunted "Wildcat" offense was brought to the NFL by David Lee, former quarterbacks coach at Arkansas.

The second I think is underrated but important. Lost in the debate about who is more innovative, the NFL or college or high schools, is their institutional capacities. It doesn't surprise me that the most sophisticated zone blocking techniques or pass protection schemes -- or even five or seven-step drop pass patterns -- are usually developed in the NFL. The margins are quite thin there because the personnel is so good and every team has a salary cap. This stuff is their bread and butter, and they will constantly tinker with it.

But what incentive does an NFL team have to just say "screw it, I'm going to do something weird." Very little. Even the moribund Detroit Lions don't really have this need; the Miami Dolphins went from worst-to-playoffs, though with a little help by being different. Different helps but we're not talking about extremes.

In college or high school, however, you have teams that are completely downtrodden, as in winless in years downtrodden. There is no reason in these scenarios not to experiment. Of course, everyone knows that Rich Rodriguez's "zone read" offense was born at Glenville State where he said his entire goal was "just to get a first down." There are a lot of really bad Division I programs, but even more bad or obscure small colleges, and thousands more high schools. Indeed, for all the talk of the "Wildcat" as a "college thing," it really was a high school thing. Gus Malzahn ran some similar stuff while a high school coach, and insofar as Houston Nutt and others had their input the shotgun jet-sweep offense which the Wildcat is but one strand of is something that has exploded at high school level but hasn't really made its way to major college football. NFL coaches would do well to keep their eye on the lower levels to see what broad, new, general ideas spring forth. (A final X factor is the issue of practice time: Major D-1 colleges have just about the least practice time at any level, and high schools of course have to spend so much time teaching fundamentals that strategy is secondary. As a result there is what I call variation by hedgehog, meaning that you get variety by having a bunch of teams focus on one or two things they do really well, compared with the NFL where teams try to do a bit of everything.)

Finally, this third issue cannot be discounted. Bruce Arians, now offensive coordinator for the Pittsburgh Steelers and former quarterback coach for the Indianapolis Colts, once did a bit on defeating the zone-blitz. His basic thought was about protecting the passer: the importance of planning for the zone-blitz and protecting the quarterback at all costs. Then, at the end he wrote: "P.S. If your quarterback doesn't make $48 million then don't forget the lead option."

Coming from an NFL guy, that's damn near heresy. Of course the quarterback he was referring to was Peyton Manning (though I haven't seen Roethlisberger run any option either), but here's the thought, expanded out. Yes, quarterbacks are incredibly important, and must be protected. You have to spend a lot of time focusing on this protection, getting it right, and calibrating your matchups on top of it all when you have freaks of nature as pass rushers. (I wrote a lengthy article about pass protection here.) That's fine, do what you have to do to protect those guys.

But what Arians hinted at is something a lot of coaches believe: instead of focusing all your energy on trying to scheme your way out of all that crazy, myriad blitzing from everywhere that causes you to drop everything week to week and focus solely on that to the detriment of the run game, then why not focus on what might deter that kind of blitzing in the first place? Like option, or certain spread sets, or other things that college teams do a pretty solid job of right now. Sometimes, rather than bang your head against the wall, there's a better way.

Now this gets into the question about letting some team hit your quarterback, and involves other questions beyond the scope of this article. No one thinks running the option with Manning or Brady is a good idea, and their passing skills are so good that it probably wouldn't be worth it anyway. But is great passing ability exclusive of great running ability? And if it is not, then does running the option significantly increase the risk of injury? How much worse can it be than David Carr being sacked countless times in a season, mostly by being hit from the blindside mid-throwing motion? I'd probably rather be hit while running the ball than like that.

The wildcat and beyond

This is where the wildcat stuff becomes intriguing. The theme for this offseason seems to be that every team is studying the wildcat or looking to install it. There's strategic reasons for this and there's practical ones.

The strategic reason is that the arithmetic doesn't lie: When you run the ball and your quarterback stands there just watching the play, his defensive counterpart can assault the runner. And even if his counterpart holds back, the runner's counterpart remains unblocked; you win games by getting the defense to commit two players to one of yours and thus gain an advantage. The wildcat -- as with the triple option or shotgun spread offense where the quarterback is a run threat -- does this. That's why I predicted back in September 2008 that the wildcat would not be "gone within a week" as several commentators so confidently explained. Indeed, it appears to be gaining momentum.

The second reason is practical. The colleges the NFL drafts from are producing these kinds of multi-skilled players, and NFL teams ought to be able to employ some of them in these schemes without having to risk their $48 million quarterbacks as the bait. E.g., Pat White. That's why this concept has potential for growth, and NFL coaches seem to embrace it now. (How bizarre though that they seem to be embracing this one rather specific branch off what is a much wider and older tree of single-wing/spread/option football. Maybe its apparent newness allows them plausible deniability about having ignored what has been put to good use for decades.)

I will have a future post delineating how I think the wildcat will be used and expanded upon this fall. Unfortunately, I don't see the storyline being quite so rosy as the NFL finally breaking down and going all out with Eric Crouch types at quarterback. I can safely predict that some of the teams that are discussing their wildcat will be completely inept with it: they will do things like going five-wide with their quarterback split out, their runningback or wideout alone in the backfield, call for no motion or faking, and then expect him to plunge into the line for some kind of great effect. That team, its coaches and its fans, will declare the Wildcat a bust. Some other team, maybe the Dolphins again, will expand the package and see success with it. But then what? The worst case -- though possibly the most likely -- will be this:

The offense will fade from prominence, and will be relegated to NFL Films productions about the "WACKY WILDCAT" days of yore, where they will show somebody running free downfield while they speed up the footage and play Benny Hill music. Then they will show a clip of someone stuffing a particular play, and the voice-over will announce that the Wildcat, like all other gimmicks, was figured out and defeated. The NFL types will nevertheless congratulate themselves for having discovered it in the first place. Someone will be called on air to talk about how it was a travesty of the game, in some bizarre platonic ideal sense.

But there is a slight counter narrative. One is that the wildcat, as some kind of hype-machine and maybe even explicit look will die down, but the concepts will infiltrate the NFL and it will finally, and slowly, co-opt ideas that have been successful in every level of football elsewhere. Some will still deride the flashes as gimmicky, but seeing as that most didn't understand it to begin with, most probably won't even notice. Take a look at the clip below: the Ravens, using Ohio State quarterback Troy Smith ran the zone-read, and the highlight guys began a small war on what to call it. (Smith also takes a rather bizarre inside angle with his run.)



Conclusion

Time will tell where all this goes. For now, however, I expect the NFL Offense to remain as indicated, with just a flew flashes of the wildcat and other similar elements. But maybe with more, and cheaper, players who can execute these schemes the NFL will be forced to adapt them to its own ends. And maybe that will even help protect its quarterbacks.

APPENDIX - The NFL Offense

Formations may differ, as will motions and a few little quirks, but basically this is what every single NFL team does. They might have a wrinkle or two per week; they might adjust the formations so they get their Pro-Bowl receiver running the route they want; they might run each play from everything from a three tight-end set to a spread formation; but it is all there. It is a partial sketch below. There are some I have diagrams, and with others I have links to old articles either instead of or to supplement the diagrams.

(1) Run game


- Inside Zone, a.k.a. "tight zone"



- Outside zone, a.k.a. "wide zone" or "stretch" (either regular blocking (shown below, diagram courtesy of Trojan Football Analysis) or "pin and pull")



- Counter



- Power



- Lead draw (draw play with a lead back)




(2) Quick passes

- Hitch

- Fade/stop, fade with an out, and double slants



- Stick (more to come on this concept)

- Spacing


(3) Dropback passes (including play-action)

- Curl routes



- Smash

- Post/Dig, a.k.a. "NCAA Pass"



- Flood/sail



- Four verticals (trips and regular), also lots of deep comebacks off the four verticals to the outside guys (either by call or read)

- Levels

- Three-verticals (either with corner routes or go routes)



- "Mills," a.k.a. Cover 4 beater



- Shallow series (for more on the drag and drive series, see here, and for a comprehensive look at the shallow stuff Mike Martz ran with the Rams, see here)



- Seam and square-in/other downfield passes like double-post



(4) Movement passes

- Bootleg. Everybody runs the same bootleg passes, one with the fullback faking the counter and running to the opposite flat, and the other the basic one with one guy to the flat after a count as a blocker and another dragging behind him.



(5) Screens

- Slow screen to RB and TE. Also will use double-screens or read-screens with the slow screen combined with either a sail or drag type route

Homer Smith on Scouting

Misconception #42:

You scout an opponent’s defense to find out what it has done.

I suppose. But what you need to figure out is how a defense is coached, how it can be played against you.

To scout, you take everything you already know, then you watch tape
hour after hour. You hope that gradually their scheme will come into focus and you can begin to piece together a game plan.

As an example, you want to know how you can go through the top of their pass defense. You analyze how they coach the ‘lid.’ You watch the feet, the turns, the positions on receivers. If you are fortunate, you find a young player who is vulnerable if you go around him to his inside and then run on his toes; or, a leading backfield tackler who can be sucked up by a TE’s block and who won’t be close to a post route.

These examples are not of what defenses they have played in certain positions or situations. They are of specific ways to beat specific defenses. When you have the specifics, you do not want to take a 60 percent chance that your play will face the defense it will beat. You want a 100 percent chance that the play you practiced against a defense will be run against that defense.

Scouting? It is a whole lot more than naming defenses and listing when they have been played.



And here's a couple of bonus quotes from a discussion with Coach Smith from Crimson Confidential:

[Homer Smith] The spread offense today features the running QB. Defensive problems come from not having a tackler ready for the QB at the line of scrimmage. . . . As long as running QBs keep winning the jobs, the spread will be the formation of choice. Someone has to tackle the QB. If that someone is looking for a post pass, the QB is going to have running room.

[. . .]

[MLH] Who do you think is the best offensive mind in the NFL today?

[Homer Smith] I just don't know. I think the best minds are in college.

Sid Gillman, "Father of the Modern Passing Game," notes on passing offense

Sid Gillman, along with Paul Brown, basically invented modern football. Bill Walsh left his stamp, but he was largely just making systematic what those two had already created. Brown, an approach to football itself -- gameplanning, huddling, drawing up plays (the modern convention of Xs and Os and diagrams looking how they do can basically be attributed to him).

With Gillman, he transformed football from the rugged, beat-em-up rugby derivative it was into the orchestrated, finely tuned passing game we see now. He basically invented the concept of "timing," and calibrating quarterback drops with receiver routes. And, unlike many such "bridge" innovators -- who connect an older time to a newer one -- he continued to be on the forefront largely up until his death: he coached many great NFL teams in his later years, most notably helping with the Philadelphia Eagles when Vermeil was there and further consolidating and perfecting the "pro-style" offense. (Basically everyone nowadays who talks about being "pro-style" is trying to be like Sid Gillman.)

Anyway, here are some notes from Gillman on passing offense, courtesy of Coach Bill Mountjoy.

Sid Gillman Passing Game

Timing of Pass:

1. The timing of the delivery is essential. It is the single most important item to successful passing.

2. Each route has its own distinct timing. As routes and patterns are developed on the field, the exact point of delivery will be emphasized.

3. Take mental notes on the field on timing of the throw.

4. If you cannot co-ordinate eye and arm to get the ball at it’s intended spot properly and on time, you are not a passer.

5. Keeping the ball in both hands and chest high is part of the answer.

6. Generally speaking, the proper timing of any pass is putting the ball in the air before, or as the receiver goes into his final break.

7. If you wait until the receiver is well into his final move, you are too late.

Attacking Defenses:

1. You must know the theory of all coverages. Without this knowledge, you are dead.

2. You are either attacking man for man, or zone defense.

3. Vs. Man for Man Defense, you are beating the Man. Vs. Zone Defense, you are attacking an Area.

4. Not knowing the difference will result in stupid interceptions.

5. Study your coverage sheets so that by merely glancing at a defense you know the total coverage design.

6. Man for Man Defenses

a. Hit the single coverage man. This will keep you in business for a long time.
b. Stay away from receivers who are doubled short and long.
c. Do not throw to post if weak safety is free unless you are controlling him with another receiver, and even then it can be dangerous.
d. Flare action is designed to hold backers. If backers are loose, HIT flare man.
e. The secret to attacking Man for Man is to attack the single coverage man who is on his own with no help short or to either side.
f. You must know the individual weaknesses of our opponents and attack them.
g. There are many methods of dropping off by deep secondary men. Each method provides a weakness – know them.

7. Zone Defenses
a. To successfully attack zone defense, concentrate on attacking the slots (X-Z Curl, Y Curl, Cross Routes).
b. Flare action is a must to hold the backers close to the line to help open up the zones behind them.

8. Exact knowledge of defensive coverage and the patterns to take advantage of these is a must.

Summary:

1. Spread the field horizontally and vertically with all 5 receivers;
2. Pass to set up the run (not the other way arouhind);
3. One-Back formations are a must.

Texas Tech run game cutups

For a team that throws it as much as Texas Tech does with Mike Leach, I get a surprising number of questions about the Airraid run game. The reason, I suppose, is that if you throw the ball a lot you need a good complementary run game that will take advantage of the defense when it overreacts to your passing game but also doesn't require too much practice time.

This topic deserves a fuller discussion later, but I was sparked when I saw these clips of Texas Tech's spring football. Video below (hat tip Tortilla Report via Double-T Nation):



Okay, you might be saying, I see some guys running around, but what does it mean? Again, this topic deserves a fuller treatment, but here's some diagrams and quick explanations of Leach and Texas Tech's main run plays.

Base



Base is essentially a "man" blocking run play that has each lineman block the man over them, and if uncovered, they head up to the linebackers. (The "fold" technique comes into play where there is a sort of "shaded" nose -- a defensive tackle who would be too difficult to "reach" for the guard -- so they can make a "fold" call at the line.) The play is easy to teach because it uses largely the same scheme as their main pass protection (big on big; back on backer) but uses drive blocking. Finally, this play is often mistaken for a "draw" -- it just looks like one when run from the shotgun.

Lead



"Lead" is your basic "isolation" play: all the linemen block "man on" or "down" and the lead blocker bursts into the hole and blocks the first man that shows; the ball carrier then cuts off the lead back's block. Tech uses this a lot when they get into any two-back set (whether from gun or those rare times under center). From shotgun this too looks a lot like a "lead draw," but it is really just one of the oldest plays in football run from Tech's funky wide line splits and shotgun.

Stretch



The "stretch" has increasingly been a weapon for Leach over the past few years. A big reason is that Leach is now fully committed to the wide line splits, so at some point in the game the defensive ends tend to stop lining up so far outside the offensive tackles and instead line up heads up or inside them, thus giving the offensive guy an easy "reach" block to hook the defender inside. As a result the runningback has an easy spring to the outside.

Conclusion

Leach's run game is not complicated and no one will confuse Tech with Paul Johnson's flexbone option teams, but they have had decentbalance (depending how you define it) over the years and the run plays are some of the most tried and true schemes around. He just uses them from his spread sets, and only when the defense is completely stretched out.

The Divide Route in the Multiple Smash Concept

The "smash concept" is extremely popular for a reason: It's a great route. And it is simple to teach. The concept is designed to defeat Cover Two in its many forms. As Cover Two has evolved (Tampa 2, "Tough Two" with the corners retreating to ten yards and jumping routes, and Cover Two-Man), the Smash has become more and more popular.

A word here about verbiage. I refer here to the "Smash concept" or the "Smash route." Both refer to a two-man combination with the outside receiver on a 6 yard hitch and the inside receiver on a 12 yard corner route. Some coaches and teams go further and actually refer to either the corner route or the hitch route as a "smash" route. Again, "smash" to me is the combination - i.e. the concept - rather than any individual route.




In any event, the quarterback has a progression read: (1) corner, (2) hitch underneath. In his progression read he will "key" the cornerback: If the cornerback sinks back to stop the corner route, throw the hitch; if he comes up for the hitch, throw the corner. The best way to describe this to a QB is that you have a progression read and you "read" your receivers. You simply "progress" from one to two. In doing this though you have to understand what guys you are "keying," as their reactions should determine your progression. A Quarterback must understand defenses and defender reactions, but at the same time there is no telling where those 11 guys on defense will go, and as long as he knows where his receivers are and if the QB and the receivers are all on the same page we can run a successful play. We tell him his general rule is to throw the corner route until they take it away (though by gameplan or defense you can tell him to always throw the hitch until they come up for it).

I won't belabor the details of coaching up the "smash" portion of the route itself. If you want to understand all the details in depth, I suggest this. See here too for more on the "multiple smash route." (Registration required) Broadly, the inside receiver will run a 12 yard corner route. He has no "reading" on the play, but he must know his techniques. First, he should identify whether it is man or zone. Against man he will need to close his defender's cushion, push or lean him slightly inside, and plant and break hard away from the defender. Against zone he wants to see who he is running the route off of. If there is a deep defender over him he must set this man up inside and jab at the post at 10-12 yards and break for the corner. If there is no one head up on him he will roll cut his route so he loses no speed. It's worth mentioning though that even if he jabs or plants and breaks we want this closer to a "speed cut," as we don't want him to lose too much speed. A receiver can do this best by "jabbing" while having his toes actually pointed where he wants to go and having his "plant" foot not outside the framework of his body. Young receivers too often step way outside their body frames with their toes pointed in the wrong direction.

The corner route will be caught between 22-25 yards downfield. The QB's job is to "throw him open": throw the ball into the open grass. The receiver must react to the ball and go and get it. Against man to man defense to the short side of the field the depth of the route will be 18-22 yards.

See the above linked article for more specifics, but we tell the outside guy he has two portions to his route. First, run a six-yard hitch route (five-steps - three big and two small), and (2) the "option" or "get open" part of his route. We simply want him to find the open spot. If the corner comes up in Cover 2 zone he will push to 6, turn inside, and work inside to the next zone hole.



If the corner is off and he turns and there is a flat defender inside, he just wants to get space from that guy. If that defender hangs the hitch receiver will drift away from him at his 5-6 yard depth as an outlet for the QB.



If the flat defender flies out to cover him he will break inside this player. We'd like him to actually climb over this flat defender because he will better be able to find the zone hole created but if the flat defender hangs back too far he will come inside slightly and settle underneath.



The Divide Route

This is all fairly straightforward stuff that most people do. The point of this article is to talk about adding a bit more of a big-play dimension to theSmash by using the "divide route," which in other coaches terminology may be a "seam read" or a "tube-read." Both the route and the "read" are simple.

The divide route involves a MOFO or MOFC read by the inside receiver. MOFO simply means "middle of the field open," or no deep middle safety. MOFC means "middle of the field closed," or is there a deep middle guy. The nice thing about this read for the "divide route" as opposed to some other contexts is that the route, hence the name, is simply about "dividing" the deep coverage and the receiver has a lot of freedom to find the downfield open grass. It's a deep stretch and it is designed to strike safeties who overplay the smash or simply get out of position.

Obviously the immediate strength of the divide route as shown is that if a two-deep safety to the smash side overplays the route, one can hit the post route for a big play. If you keep the go route on the backside (as diagrammed) and both safeties overplay the Smash side then the "Go" might be open for a big play. The simple reality is that a Cover 2 team really cannot cover this concept effectively.

Against a Cover 3 zone the QB's "peek" is the seam backside. Before the smash part of his progression, he wants to get the F/S moving and hit the seam.



Running the divide to the trips side is even more dangerous. Any team that tries to play Cover 2 to the trips side will struggle mightily. Many defensive coaches instruct their kids to simply check out of Cover 2 against a trips look. Observe that the "divide" principles governing that inside receiver tells him that he will run more of a "skinny" post here inside the Cover 2 safety to break the deep coverage but avoid the safety on the opposite hash. If there is no deep safety the receiver has lots of freedom.

This is because, again, the governing principle of the "divide route" (one reason I like to call it this instead of a "seam-read") is that you can largely just tell the receiver that he has the area between the hashmarks to work to find the deep open vertical grass. A more advanced technique applies if the defense drops super deep so that he cannot effectively "divide" defenders. This will be done by gameplan, but if that is the case we will essentially let him "throttle" down a bit in the voids and the QB will still look to throw it in the open grass, but simply in the open grass in front of those deep dropping safeties.

In any event, see below for how the divide route will work against MOFO and MOFC defenses.

Cover 2:



Cover 3:



Now, what if it is a MOFC defense but that free safety is flying over too much? Well now it's time to be a good Ball Coach and tag the inside receiver on a "middle-read" route. I have previously explained that route here. The similarity with the divide is a post route against MOFO. The difference is a square-in or cross against MOFC. So if that free safety flies over, he will cut inside that guy. Observe that this is the exact same principle we used for that outside hitch receiver.



Backside hitch

Here is a last aspect to the play that I am a big fan of. I think the play is very effective if you keep the backside player on a hitch, particularly in trips. This gives you a great look against any soft coverage. When you do this you ask your QB to be a ball player and get the ball to the backside receiver if the defense gives it. (In other words, it's probably soft Cover 3.) If it's not there he looks over to the smash side and works his normal progression: Peek at the divide route, then work the smash combination.



Conclusion

This is a simple, well designed play that is both a ball-control, high percentage play, but with the divide route and the corner route it has great big-play potential. If the defense plays soft you will take what they give you, but if they play any kind of two-deep or if their safety gets out of position you will make them pay.

Rock-Paper-Scissors, Edgar Allan Poe, and Play Selection

Despite the lofty title, this post focuses on the narrow topic of calling the right play in a football game. Coaches spend an enormous amount of time studying film, determining tendencies, creating gigantic scouting reports for each opponent, and then distributing them to their other coaches and to players who do not read them. Barely sleeping is a badge of honor, particularly at the highest levels, we are sure that more work equals more success.

This is surely true, but how is time best spent? And how should the entire idea of "play-calling" be thought of? Despite all the time spent on preparation, when asked most playcallers, such as Notre Dame's Charlie Weis, say that playcalling is "more art than science." If so much of it is gut feeling and chance during the game, then maybe the better strategy is to get some sleep during the week. I'm kidding, as I put a high premium on preparation, but can active playcalling do more harm than good? And what are the boundaries to knowledge and insight into what the other guy is going to do? Is it ever better to pick your call or choice randomly? Don't we already do that quite often?

Poe's Purloined Letter

In Edgar Allan Poe's the Purloined Letter, a character recounts a story of a young man who excels at game called "odds and evens," more popularly known as "matching pennies." The game is a two-strategy version of rock-paper-scissors: Each player secretly turns their coin to heads or tails and then both reveal their choices simultaneously; if the pennies match (both heads or both tails) then one player gets a dollar, if they do not match then the other player gets the dollar. As told in the story, the young man quickly sizes up his opponents, gains a psychological advantage, and amasses a fortune by outguessing his opponents.

I suppose all playcallers think themselves like the young man, but most are probably more similar to the suckers. But here's the rub: The suckers could nullify the young man's psychological advantage.

How?

By choosing randomly. If the suckers put no thought into whether they chose heads or tails, they would do better than if they tried their best to outthink him. They would break even--a fantastic result against the world's greatest matching pennies player--an unnatural genius who, according to the story, would go through lengthy Sherlock Holmsian deductions to determine if his opponent was going to choose heads or tails.

This is a breath-taking result. But it is also scary--would I be better off picking my plays entirely randomly?

Rock-Paper-Scissors and the Bend-But-Don't-Break-Defense

Playcalling, at least oversimplified, is a lot like matching pennies, or--for a more common game--rock-paper-scissors. If I choose rock and you choose scissors, I get a first down. If I choose rock and you choose rock, I maybe gain a couple yards. If I choose rock and you choose paper--whoops, I just got sacked and maybe fumbled too.

A lot of football games come down to who has the bigger rocks and scissors (more talent), but tough, highly competitive games really do come down to whether you picked paper vs. his rock or vs. his scissors. But how many supposedly great calls were just luck? Probably a lot. We try to make educated guesses, but there's something to be said for going random.

Let me backtrack for a moment. John Wooden, the best basketball coach ever, talked a great deal about focusing on his team. Norm Chow, now offensive coordinator with Tennessee, mentioned how very often he really does not know what the other team is even running right then, and it would be hubris to act like he always knew. When a playcaller says that it is more art than science, he's really just saying that he's out there making (educated) guesses, but guesses nonetheless. Wooden's insight about focusing on his team is that time is best spent byfocusing on what you can control: developing your own talents and self-scouting--to avoid situations where you do become predictible.

The message? When you're scouting you're looking for sure things. Times when you know the other team is going to blitz, or is going to run that one screen pass they like or whatnot, and the best thing you can do to win games is make sure that you don't have any of these true "tendencies" that your opponent can act on. The fact that the other team knows you run it 37.4% of the time on 3rd and 4 1/2 on your own 43 is simply not useful information because it doesn't materially narrow their decision-making. If they know you only run it 3.74% of the time, that is material.

To carry the metaphor, you help yourself the most by preventing your opponent from ever knowing that if you lose twice in a row, you always shoot rock. You may still lose three in a row, but you've given him no advantage. Again, this is powerful. Even if you are playing the world's greatest playcaller or rock-paper-scissors champion, you can still break even, and then wait for those rare times when you know they are going to blitz, or come out with scissors, and hopefully carry the day.

So what's that about the bend-but-don't-break? Imagine: You are playing rock-paper-scissors. Whoever wins gets $1, if you shoot the same no one gets anything, but if rock wins over scissors, the winner get $10. What will this do to the game? Anyone with any sense is going to try to play rock more often than anything else and rarely, if ever, play scissors. If you shoot scissors you can win $1, break even, or lose $10. If you shoot rock you can lose $1, break even, or win $10.

This is the theory behind the bend-but-don't-break defense (and to some extent the more wide-open offenses). The idea is that if you play a gambling type defense, you may win more than you lose, but when you guess wrong, you give up a TD or a big play. The bend-but-don't break will concede by giving up many short passes and runs, and hope not to give up the big play. I am not saying this is a superior strategy, and in fact may be a long-run loser, but it's important to understand the theory. The person practicing that defense recognizes that they will probably be wrong more than they are right, but they think it will be worth it in the long-run--the risk is acceptable to them.

Application

This "mixed strategy" thinking is not meant to supplant gameplanning. (Offensive Coordinator: "Sorry Coach, I'm not doing any work this week, Chris's website told me to just go out there and 'wing it.'" Head Coach: "You're fired.") Indeed, much of gameplanning should fit into your estimates of what will and won't be successful, and then you can engage in a bit of the decision to run or pass I detailed in this post.

What it does is it gives you a place to start. You should have a general equilibrium strategy based on your talent and what you emphasize going in week to week. You can hope to be a 50/50 run/pass on 1st and 10 team, with focuses on quick and intermediate passes and power runs. This is your so-called "identity" and your practices will focus there because it is what you do the most. Then you "kink-it," or skew your weekly plan to the things the defense is weakest against. Who do we run against? What coverages will we see the most? Do they blitz a lot?

Another important application is the "intelligent" mixed-strategy. For example, you face a team that runs the gamut of coverages: Cover 1, 2, 3 and 4 and man and zone and every kind of blitz and they also drop 8 guys into coverage sometimes. But you notice that if you line up in a "trips formation" they will only play Cover 1 or 3, then you have significantly improved your chances. You still don't know for sure if they will be in Cover 3 or 1, or if they will or won't blitz, but you r mixed strategy has been narrowed to a better range of possibilities.

Yet, most teams know their own weaknesses. Most defenses match their weakest defenders with their strongest, not content to let half their defense get run over every week. Further, you get into that neverending mental game: I want to throw quick routes because he likes to blitz. But he knows I know he likes to blitz, so maybe I will throw off deeper drops because his defenders will be looking for my quick passes. But then maybe he knows that I know that he knows that I know he likes to blitz, and thus will blitz anyway countering my counter. And so on. Do I have any special proficiency for this? What if the defensive coordinator is straight out of the Purloined Letter? Remember Norm Chow: if you are so certain of what the other team will do or you have a true read on the opposing coach, it's probably just you being arrogant.

Conclusion

Imagine you are a wing-T youth coach, and you have only three plays: the dive, the bucksweep, and the waggle (bootleg). You can win a lot of games simply by selecting those three plays practically at random; each perfectly counters the other. Then, every so often, you'll see that moment when you know that the waggle will be there. The corners are coming up for the run, the receiver has a mismatch, you know the QB will break contain, so you call it--TD.

Simplified, this is where gameplanning, play-calling, and deception all intersect. Although I've focused on play-calling from the sidelines, I recognize that in modern football playcalling differs from rock-paper-scissors in that it is not a static, simultaneous "now show it" game.

In football you call the play, then show a formation--thus narrowing the range of possibilities--then the play begins, and with good recognition both the offense and defense can react to what the defense is doing and put themselves in position to win. Many very good offenses try to "cheat" on good playcalling by calling everything from the line of scrimmage, and the run and shoot and the triple option try to "cheat" even further by putting a premium on "reading the defense" to make themselves right all the time. Many good defenses operate on similar principles. The important thing to remember for now is that deception and duplicity are your best weapons to prevent this kind of targeting, and once you've done that, you tilt the advantage back in your favor, and the "mixed strategy" reemerges as your best course. And again, if you can limit their strategies by formation or design, then you can improve your mixed strategy by being able to choose the things that defeat their known range of possibilities, rather than than having to be totally random.
