Which Ohio State Buckeye do you dislike the most? Naturally, there are lots of reasons to hate the Buckeyes. If they wear scarlet and gray, I don’t like them already. But some are tolerable, and some aren’t.
My vote goes for Jim Tressel. There are players I disliked (Katzenmoyer, Pryor, Clarett, Justin Boren, etc.), but Tressel passed himself off as a good, level-headed guy. But it turned out he was dirty, let players get away with things they shouldn’t have been allowed, and then tried to cover it up to save himself. At least some of those guys are up-front about their idiocy, but Tressel was two-faced about it.
