The Clay Travis article about the coaching search made it clear that Hamilton keeps and constantly tinkers with a list of potential replacements for his coaches. There's no reason to think he's quit doing that. I just don't think he could get anybody on it.
I don't disagree with you about the quality of the hire. I think the best thing to do, once Hamilton was down to the dregs of his list, would probably have been to name Kippy Brown interim coach and be first on the coaching carousel next year. But had Hamilton done that, we all know that there's a good chance he wouldn't have still been around to make the hire next year. I can't exactly blame the guy for making a move, ANY move, to save his own job. I also don't disagree that maybe that decision should have been taken out of Hamilton's hands, especially once it became obvious that he was being repeatedly turned down in his coaching search, but with UT not currently having a president, ousting Hamilton wasn't likely to come together that quickly. Simek isn't going to fire Hamilton on his own.
The fundamental problem is that, for various reasons, the roster and depth situation at Tennessee has been brought to the point where we can't even attract promising coaches from mid-majors. Leaving Utah for Tennessee ought to be a no-brainier. Leaving TCU for Tennessee ought to be a no-brainer. Leaving Air Force for Tennessee ought to be a no-brainer. But right now it's not.
