The really, really good football coaches are not happy people. Their profession demands perfection, discipline and relentless attention to detail.
Apparently, it's impossible to be all that and also be happy. Even winning is a problem, because you never play the perfect game and because players become overconfident.
I've been thinking about this since Alabama won their title. Nick Saban is a dour, restrained, focused man. He doesn't smile a lot. Then I thought about Bill Belichick. He's not too different. And Jim Harbaugh. And Vince Lombardi.
And now Bill Walsh.
There's an excellent story on ESPN's site about how Walsh's book has become a coach's bible. But the real story is what a miserable, obsessed perfectionist Bill Walsh was. He quit for the same reason Lombardi did: it was eating him up. He didn't even enjoy Super Bowl wins.
Football rewards grinder coaches. But it seems to me that a lot of what is being ground up is the football coach himself.
