The way he treated the players during those first two seasons was inexcusable.
I can understand getting upset at a given player. Hell, even Lou would grab your face mask and chew you out.
But in Lou's case, he throw you back onto the field and demand that you do your job, giving you plenty of chances to do so.
In Kelly's case, if you weren't his right kind of guy, he'd bench you at the first sign of a mistake, and let his right kind of guy play the rest of the season.
The way he turned deep purple when calling Dayne Crist every foul name in the book (and some that weren't), showed how he couldn't be decent to those guys.
On the other hand, even after multiple boneheaded throws by Tommy Rees, he coddled him...
