Funny, I'm sure you think they are student athletes too. Winning is all that matters to the football coach, boosters, and AD. You could be the best coach at getting guys to graduate but if you lose more than you win you will be fired.
This topic has been argued this way by fans of other teams for a long time so its pointless. Your opinion is that Tressel was a terrible guy who did anything to win football games. That's fine, he got caught lying to the NCAA about not knowing of rules violations so if you want to believe that you have leverage. Mo Clarette was an idiot and said things about Tressel after he was kicked out of school so that usually is another reason why Tressel was a cheater. I'm ok with that, of course you would have loved Tressel to be the coach of UM during those years with all that success and if you wouldn't that is a lie.
But to think that stuff like this doesn't go on at every school is pretty funny to me. You don't think that Denard gets special treatment?
I would never want a scumbag like Tressell coaching at MIchigan, whether he won 10 championships or zero.
