I guess it is all a matter of how you view the Vols current situation. IMO the only real slam dunks (picks that would not have failure of any kind) would be Gruden or Davis. Kiffin is not quite in that category for me, though I am confident that he would be a good hire. After that it is safe to say (IMO again) that we could be looking at a transitional hire even though the BOT and Hamilton seem to be swinging for the fences.
Without a doubt, hiring Strong or Gill would result in some very positive PR for the University. In many ways it would be no less risk than hiring a guy like Muschamp.
