I'm stuck on this one. I really don't like the guy, but he can coach and he does know how to win in the B10. His style of football would fit Iowa very well, and obviously Iowa means a lot to him.
So ultimately for me as long as he came to Iowa and won without doing anything the wrong way I would be okay with it. By "wrong way" I mean I would hope he's not doing anything deemed illegal by the NCAA or committing any major ethical violations. Even though he doesn't have a track record of doing that his personality just comes off like someone who may try.
Like I said though, if he's going about things the right way I could stand his arrogant attitude and BS if he's making my favorite team a consistent winner. It would definitely be nice to see someone with a little more emotion on the sidelines. Someone who isn't afraid to step on an opponents throat.
