Is humility.
Martz' downfall was in his insistence that it was his scheme that won games. Not the players who brought his little x's and o's to life. He also seemed to relish in this idea that his offense would *dictate* to each defense how each game played out. "We don't take what they give us; we take what we want." That was bravado. Pure and simple. And it also placed a target on the chest of each skill player on those teams as the games and seasons rolled by.
McVay? He is a *tactician*. He's a thinker. A planner. He is unafraid to tweak his philosophy to fit a game. A situation. A player.
For my money, he's far more in-tune with the offensive theory of Bill Walsh than Mike Martz.
Which only makes sense ... since his grandfather was 49ers' GM when Walsh was changing the game of offensive football.
I know you love Martz. And he has his place in NFL history. Unfortunately, his ego and ... I guess what you'd call his inner-rage ... got the best of him. He failed to respect the things he needed to that would have brought him wider acclaim.
I don't sense McVay is that way at all. This is a humble, extraordinarily smart, flexible and innovative young man ... who respects the game, the people he coaches with and against and the players he coaches and coaches against.
