Football, decisionmaking, and the brain

One of the many reasons that football is the greatest of all games is that it encompasses every type of decision we humans are capable of. There are the carefully planned decisions coaches make leading up to a game: Who should start? What will our opening plays look like? How can we defend against this scheme? There are snap, in-the-moment athletic judgments: Who has the ball? Is the receiver open? Is the hole inside the guard or outside it, where will the running crease be? And there are what I call "golf swing decisions," which combine the reflective moment with the snap-athletic judgment: When should I snap the ball to time up with the motion man, while still getting off a good snap? I need to blitz through the A gap between guard and center, but what if they are in a slide or gap protection scheme and close that off? Should I try a rip or swim type move? I'm receiver and need to run an out route, but when if the cornerback comes up and jams me and I need to run a go route, how should I use my hands, eyes, etc?

Football shares the need for snap, athletic judgments with most other sports, like basketball or soccer. But it is unique in that every four-to-six second contest is preceded by a complete stop where everyone has some time to collect their thoughts -- or to heighten their anxieties. Baseball has some of this, insofar as pitchers have to think about the type of pitch they want to throw and where, but even if batters could get a handle on the pitchers' rhythm, the human brain cannot rationally break down what a throw is when it is coming in at 90 miles per hour -- it must be an instinctual swing-or-don't-swing response.

In a later post I plan to break down more of the cold, rational, time-intensive decisions and where those decisions break down. I'm interest in which decisions are "predictably irrational," and can they be fixed? Also, what heuristics do coaches and sometimes players use that correctly and incorrectly inform them? But today I limit myself to the raw, instinctual, athletic intelligence that football players must possess or be gone.

Athletic intelligence

Very rarely does a football player use their "rational brain" during a game the way solving a math problem would. Jonah Lehrer, in his book How We Decide, tells a story about Tom Brady. He describes Brady's mindset as an elite quarterback in the pocket which -- especially considering that quarterback is considered maybe the "most intellectually demanding" of all sports positions -- is surprisingly instinctual and unthinking. He drops back and scans his receivers. He gets to one and simply lets the ball go. Brady is asked: "Why did you throw it to that guy?" He replies: "I just felt like he was open." That's it. That's it?

Yes. There really can't be much to it than that. A QB might have an idea of where he might throw it, as his rational brain can do some early legwork, but the ultimate decision is by the emotional, reactive parts of his brain. (Lehrer and others get into the neuroscience of this, which I am not equipped to discuss.) The brain, getting some kind of positive feedback, tells the muscles to release the ball. And how could it be otherwise? These decisions happen much too fast for any person to coldly and rationally walk their way through it. The quarterback must simply know.

(Note that this is not saying that emotional or instinctual intelligence is better than rational intelligence, or vice versa. It is that some situations call for different types of decisionmaking. Indeed, my general assumption is that attempts atrational decisionmaking is usually better (which is in fact not always true), but many times, including in sports, there is no time for some sort of reasoned analysis. Contra this post then with Gladwell's Blink: The Power of Thinking Without Thinking.)

This need for amazing decisionmaking that is nevertheless largely reactive is one reason why it is so difficult to evaluate quarterbacks -- or any player. You only get so far by asking Tom Brady "why did you throw it to him" when his answer is "I felt like he was open." And that's with quarterbacks: obviously safeties on defense, or linebackers, or linemen, runningbacks, all rely more or less on this raw emotional intelligence rather than something coolly rational. How do you measure that kind of instictive, non-descriptive intelligence? Yet if a guy doesn't have it, he'll just kill your team with bad "decisions."

Yet what does the NFL use to evaluate its players' intelligences? The Wonderlic Test. Having just seen the above discussion, where not even Tom Brady's athletic intelligence is necessarily rational or describable in the way a mathematician's or philosopher's is, how useful can this test be? Yes, it can help eliminate some total knuckleheads, in that NFL players must learn large playbooks (and in college must be able to stay eligible lest the idea of student-athlete be completely severed), but most of what makes them elite or not is based on how they react.

When a linebacker just knows that a play-action fake is indeed a fake, or that the runningback still has the ball after misdirection from a wide-receiver faking a reverse, he uses very little if any of the skills tested by the Wonderlic. Yet I do sympathize with the NFL: how else can you test this stuff? But what if having a really high rational intelligence not only didn't help or didn't test what made a player good or great, what if a heightened analytical ability made a player worse?

Eli and Peyton Manning and David Foster Wallace

This is where the "golf swing" intelligence can come in; it's also often called "paralysis by analysis." Think about getting ready to swing a golf club while a friend or pro tries to coach you up. "Keep your arms straight." "Turn your hips." "Keep your head down." "Keep the club face square." "Choke down on the club." "Loosen your grip." "Bring your arms through before you start moving your shoulders, but keep your head down." "Keep the club face square but also rotate your wrists so that you finish with a good rotation." Etc. A friend of mine told me that he had one such session, where a pro told him about ten things to do before he swung the club, and then just sat there a minute before swinging. The pro said, "What are you thinking about?" His reply, "All the stuff you just told me."

Now here's a fact you may not know.

Question: Which Manning brother had the higher Wonderlic score?

Answer: Eli. By a long shot.

Peyton's score was perfectly respectable: a 28, higher than average for his position in fact. Eli? A 39, which put him in the 99th percentile of all NFL players -- as well as the 99th percentile of all two-million test takers. As Charlie Wonderlic said of Eli's score, "There's not a job on the planet that requires a person to score at that level." But who would you rather have making decisions for you on gameday? I thought so. Of course, Eli has improved, but there's no question that Peyton is the more consistent decisionmaker. Indeed, all too often Eli looks uncomfortable, like he has overthought the whole process of "just throw the football to the open guy." (Tom Brady, who scored a 33, is also not known as a hyper-analytical guy, though some of that is hearsay.)

And again, this is quarterback, supposedly the marquee thinking-man's position in all of sports. Obviously defensive backs and tight-ends don't need the same level of analytical ability as quarterbacks do. And yet, after games, what kind of questions do reporters ask? You got it: "What were you thinking out there?" "What did it feel like?" And the answers are almost always completely banal (and where they are not they are probably fake): "I just take it one play at a time. Keep doing my best. Focus on the basics, you know." "I'm just really happy. It feels great to contribute. We've all worked really hard."* Really, of what use is it to ask Santonio Holmes what was going through his mind when he leaked out to the corner of the end zone and made a miraculous, extended catch to win the game? "You know, I had been thinking about this great Henry James novel most of the time, but I regained focus when I saw the ball's trajectory and calculated that, based on its particular rotation speed -- as far as I could detect -- I should place my hands in a particular way and I also calibrated my feet so as to minimize the chance that if I slipped I might get any white ink on my shoes so that the ref might call me out." Uh. Holmes was plenty eloquent after the game, but the bottom line is: the ball was in the air and he made a fantastically athletic play. Any analysis might have been counter productive.

The late David Foster Wallace discussed this in a review he did of a biography about tennis prodigy Tracy Austin. I think it well sums up the dilemma that players, coaches and fans have in trying to understand athletic genius, which not only might be distinct from rational genius, it might be the antithesis of it.

It remains very hard for me to reconcile the vapidity of [an athlete's] narrative mind, on the one hand, with the extraordinary mental powers that are required by world-class tennis, on the other. Anyone who buys into the idea that great athletes are dim should have a close look at an NFL playbook, or at a basketball coach's diagram of a 3-2 zone trap . . . or at an archival film of Ms. Tracy Austin repeatedly putting a ball in a court's corner at high speed fro seventy-eight feet away with huge sums of money at stake and enormous crowds of people watching her do it. Ever try to concentrate on doing something difficult with a crowd of people watching? . . . .

It is not an accident that great athletes are often called "naturals," because they can, in performance, be totally present: they can proceed on instinct and muscle-memory and autonomic will such that agent and action are one. . . . They can withstand forces of distraction that would break a mind prone to self-conscious fear in two.

The real secret behind top athletes' genius, then, may be as esoteric and obvious and dull and profound as silence itself. The real, many-veiled answer to the question of just what goes through a great player's mind as he stands at the center of hostile crowd-noise and lines up the free-throw that will decide the game might well be: nothing at all. . . .

This is, for me, the real mystery -- whether such a person is an idiot or a mystic or both and/or neither. The only certainty seems to be that such a person does not produce a very good prose memoir [or descriptive post-game interview]. . . . It may be that we spectators, who are not divinely gifted as athletes, are the only ones able truly to see, articulate, and animate the experience of the gift we are denied. And that those who receive and act out the gift of athletic genius must, perforce, be blind and dumb about it -- and not because blindness and dumbness are the price of the gift, but because they are its essence.


This seems backed up by experience. Great players do not always make great coaches (or announcers), and often the "smartest" kids are "dumb" athletes. I will finish (for now) with a quote from a friend who is a high school coach, which I think for now provides about as good a summation as any of the awkward interplay between thinking and doing, "such that agent and action are one":

Give me the 2.5 GPA kids. I'll take them all day, everyday. Smart enough to know what's going on, too dumb to know when something is going to hurt, and not smart enough to remember what hurt last time.


*FN: These quotes are also roughly paraphrased from Wallace's fantastic essay, but since it's all so common anyone who has ever seen a post-game interview could fill these in.

This is a great piece; football does require more thinking than most sports, yet so many people see it as a less intelligent pursuit.

Thanks for discussing why football is, indeed, smart.

One cannot overlook experiential knowledge. That is, a body of experiences in a particular realm that one evaluates over time, from which he is able to build a data base of positive and negative outcomes.

Just because an athlete does not, or is not able to, articulate the processes by which his decisions are made does not preclude the fact that these processes are taking place. The evidence is seen via successful plays over time. Honest-to-god knuckleheads disappear from the sport.

In this way I liken a quarterback's "being in the moment" to playing jazz. Western music is based upon a predictable series of scales, modes, and notes. Jazz uses these scales, modes, and notes. But jazz also calls for improvisation. Therefore the player must use his experience from all his previous jam sessions to make decisions about which notes will go in a pleasing way with chord changes, and which notes are likely to create dissonance. This is not to say that dissonant notes will not be played. He might be going for that effect. But at least the player is able to predict the outcome of the chosen notes on the end result.

So the good quarterbacks are able to draw on all those years of peewee football to the present to make educated assessments about "which guy is open."

With the way that eye-tracking software has improved (and even body tracking, a la Microsoft's new Xbox add-on called "Project Natal"), there must be a way to set up physical tests for players. Set them up in a VR world and see how they react to specific stimuli.

Track their eyes as a play unfolds. Or, run the first couple seconds of a play and see if they recognize the play action (for defenders) or a zone blitz (for offensive players). These can be done to a certain degree with workouts, but you risk injury with live bodies, it's tough to track eyes (which aren't always looking where the head is pointed), and the data is likely to be heavily influenced by the qualitative.

It'd be pretty complicated to set up, but I would think something like that would be of more use than a written Wonderlic-style test.

Jon said...

Excellent. There is a recent book titled Simplexity that toughes on the complexity of the various sports.
In fact, your mention of Tracy Austin reminded me of this, it mentions tennis as a game that is basically reaction. Kluger, the author, calls baseball and football the two most complex sports.

Year2, I read your comment yesterday and you may have stumbled on a business opportunity, if you are computer programmer.

Astronauts, civilian and combat aviators, and U.S. combat ground forces all use simulators to prepare for future endeavors. The rookie astronaut has never "flown" in space before, so the only experience he will have about space flight is what he gets in the simulator. There is no "banking" during turns in space as he experienced in his previous flying career.

One of the reasons freshmen rarely quarterback a college team is because there is a steep learning curve based partially on a quantum leap in skill level between the general high school player versus college player.

A high school QB has learned the general closing speed, jumping ability, and overall skill level of high school defensive players. He will have to reset his parameters when facing an SEC defense.

The same learning curve takes place between college and the pros. Each time, the quality ratchets up quite a few notches as the gene pool heightens. The smart QBs learn, adjust, and stay in the game.

Simulators could be used to evaluate potential talent, but also to enhance the talent of players. We know the value of watching film to prepare for an opponent. We learn likely scenarios, offensive and defensive schemes, and can zero in on the skills of individual players.

Simulators can mix and match players and plays, set up specific scenarios, and create unknown situations. It would be these unknown situations which might be used as possible predictors of individual football aptitude.

Frankly, I don't know the value of the Wonderlic other than evaluators can see how generally smart a guy is. But does the intelligence measured by the Wonderlic transfer to football aptitude? I dunno.

Colleges rely on SAT or ACT tests as predictors of success in college. The military uses the ASVAB to determine aptitudes in a wide-ranging set of domains.

But when scores range from 15 to 30 in successful quarterbacks, predictability is far from certain. I guess if you got a 2 they could safely say, "No."

@Year 2 and KungFuPanda9

I believe the Army football team used a sort of simulator, based on a video game, to train their players in recent years. The idea was to give players what amounted to mental reps instead of physical reps, because the players were so exhausted from their primary daily responsibilities as cadets.

In addition, Colorado tested a system this spring where video cameras were attached to quarterbacks' helmets in order to record exactly what they were looking at in their progressions. The film would then be analyzed by coaches and studied by the players, ultimately with the goal of improving their decision making.

Mike said...

Awesome post. It reminds me of something Paul Johnson was asked when in his first spring at Navy:

Q. Have they absorbed your offense pretty well, obviously you have smart kids.


A. It's been okay, I think the attitude is good. It's like I said before, some pick up things better than others. Being smart in math and science doesn't mean your smart in football. We have some guys here who are really football smart, and some that aren't. Just like every place I've coached. I've seen guys with 800 on the SAT or 700 that were football smart. They picked up football fast.

ScottN said...

Part of intelligence is synthesizing all that training. One of my favorite quotes from last season was:

After Alabama broke from season-long tendencies during the SEC Championship Game to run a heretofore unseen pass pattern, Brandon Spikes soon came to the sideline in search of defensive coordinator Charlie Strong.

"He came over and said, 'Coach, you never showed us that play,'" Strong said. "I told him, sometimes you just have to improvise."

Ted C is Me said...

Chris: Great stuff as always.

See Homer Smith's third bullet below (from his outstanding manual on organizing pass patterns) for a different take on the same point:

-- Passers get snapshots of the defense, not video clips -- their eyes stop and start, fixing on receivers, defenders, or areas/gaps between defenders;

-- With rhythmic fixes, a passer can see the whole field in the time that decent pass protection will provide him -- say, 2.5 seconds.

-- A passer can sense danger based on past conditioning (i.e., interceptions), and his reflexes can stop him from throwing the ball into danger;

-- Learning to check his throws (pump-fake) and look off defenders is more important than "quick release", passer height, high ball release, etc.;

-- Passers should look at an area only for a fraction of a second to prevent giving defenders easy reads;

-- Therefore, pass routes must be packaged together in a way that allows the passer to sequentially read the defense in quick fixes.

...so perhaps Brady's "feeling" that a receiver was open was based on prior experience, both positive and negative.

Completely agree with Kungfupanda. After reading Blink a while ago, I came to the same conclusion (and have generally been unimpressed with Gladwell).

I would also add that it's probably unwise to think of the Wonderlic as a typical IQ test. Instead of differentiating across the spectrum, it seems geared to differentiate the masses from the very bottom. (Google 'wonderlic' and take a sample test: the questions are not difficult and there's only marginal time pressure to get a completely respectable score.) The result is that folks who are woefully unprepared and/or learning disabled will perform relatively poorly. Clearly you don't want to draft someone who's unwilling to prepare, and a red flag regarding learning disabilities requires at least a follow up interview to see if the light's on (particularly if we're talking about the QB position... cough Vince Young cough cough). NFL teams seem to follow this pattern; preference is not given to high scorers, but low scorers have some explaining to do. Contrast with other standardized tests, like the SAT or ACT, which seem designed to separate the best of the best.

I think the problem with using a simulator for purposes of draft evaluation is that it presupposes that the player has been exposed to and coached on the reads an NFL team will expect that player to make. For example, you wouldn't expect a QB after 5 years in a Rich-Rod spread-to-run offense to step into a simulator and make all the right reads in a pro-style offense. In other words, the simulator measures whether a player has been taught (and presumably is used to teach) while the Wonderlic measures whether a player can be taught (by identifying those who won't put in the work and/or are learning disabled).

Stan said...

Chris,

I think that there is far more involved than "intelligence". Even what you call "reactive intelligence". You might want to expand the topic to the functioning of the nervous system. To be a successful baseball hitter, one has to have an extraordinarily quick nervous system. If the time from "decision" to "swing" isn't extraordinary, all the eye-hand coordination, practice, etc. won't make you a MLB hitter. You would be reduced to being a guess hitter. Otherwise, you're just too slow.

For a QB, what we think of ordinarily as intelligence does matter a lot. There's a lot of memorization, understanding and recognition which comes into play. And as with anything else, study, hard work and preparation makes a big difference, too. (see Peyton vs. Eli).

But there are elements which are also similar to a baseball hitter. A baseball hitter improves his ability to pick up the spin of a curveball, etc with years of experience and practice, but that can only take him so far. A QB can get better at understanding, anticipating, reading, etc., but there still comes a point where the brain has to be able to process the blur, see the field, make discriminating judgments and decide to act. This is more in line with what you have described as "reactive" intelligence.

But even if his brain can process the blur and reach smart decisions on time, he may struggle if his nervous system isn't extremely quick in translating the decision to his muscles. He may be late delivering the ball because his body is literally late. If so, he wll have to try to anticipate or "guess" to compensate.

Does the Wonderlic help identify an important quality for QBs? Sure, part of the intelligence needed to understand the game. But just as a simple eye test may determine your vision is 20/20, but fail to measure depth perception, etc., there are other aspects of brain function which are important to a QB.

Tim James said...

I wonder if there is a left/right brain thing going on with instinctual athletic decision making. It's the difference between analyzing and synthesizing, or managing and leading. Perhaps the best way to judge a football player would be how well he did in art class?
