Both lost some credibility to me. Two big personalities in the room who don't like to be told what to do. Colin needs to settle down and Harbaugh REALLY needs to learn to play the game.
I feel like Harbaugh is a grab bag of emotions; one day he's motivated, the next he's insane, and the next he's passive aggressive. Not really the face you want of a program, but if he wins all will be forgiven.
