It all depends on who we can get in for interviews at this late date. I personally think that giving Tressel a shot at redemption wouldn't be that bad of a thing, politically speaking. He would be an instant shot of credibility, though, even if he was only here for 3 or 4 years.
I'm far from a coaching guru like some of you guys, but I think Jeff Jagodzinski is probably the number 1 target on my list.
One name I have not heard is George O'Leary. I know about the kid who died during practice, and the Notre Dame resume flap, but he has done good things with the UCF program. His kids perform academically and he is a no-nonsense kind of guy, but he is getting up there in age - 65?
