There are some coaches who I feel get more praise than they deserve, but I don't generally dislike them for it. I did really like Jim Tressel a lot, but if he was still coaching, I'd say he's the one I dislike.
Gene Chizik, too. It's one thing to be pious, it's another thing to be a pious fraud. However, Chizik is taking that to another level right now. It's unreal how far he's running with the God thing. It's like he's asking to be exposed.
