Jim Johnson, Philadelphia Eagles defensive coordinator extraordinaire, has passed away due to cancer. Johnson coached some great defenses, and of course his legacy will be carried on by guys like Steve Spagnuolo who learned under him.
Johnson was a 4-3 guy, and while his protégés took many lessons from him, he will be remember for his aggressive, blitzing defenses. Spagnuolo is more of a zone-blitz guy, but Johnson was always willing to play man defense and blitz safeties and linebackers from anywhere. Indeed, as I've mentioned before, Johnson essentially put the first nail in Steve Spurrier's coffin when his Eagles defense blitzed Spurrier's Redskins -- fresh off a thirty-point game in their opener -- into utter oblivion. From then on, every coach in the league had that tape to put in. Johnson figured out exactly what protections Spurrier was using, and dialed up the right blitzes. But Spurrier was hardly alone in being schooled by Johnson.
He will be missed.
