I figured he wasn't going to last long when I watched him during the game down here in Jacksonville. When I went to the games in Baltimore a few years back, Cowher was all over the sidelines, yelling at players, cheering players, etc. This year he stood there like his feet were stuck in cement through most of the game.
I think Cowher felt that he had silenced his critics by winning a Super Bowl and had nothing left to prove. There's nothing wrong with that, but if that was the case he should have quit last year and let someone else push the guys back to the Super Bowl this year.
