A No comment works just fine.Fair enough, but what is he going to say? Yeah, I'm planning to move on, or I'm highly interested in X job, etc.?
Has ANY coach EVER come out and admitted any of that when asked about a certain job opening they've been connected to in the rumor mill? Not that I can recall. They always downplay it or deny it.
Not that it'll ever happen, but I'd take Saban at Iowa if offered the chance.
