my top 3, not in any particular order: Spurrier (only if jr comes with him), Skip Holtz, Jim Leavitt. Jim Leavitt seems to have a knack for developing quasi-good talent, granted it is in the Big East. Skip has done fairly well with ECU, if he had better talent I think he'd be more successful. And Spurrier, that is self explanatory. Especially if JR. came with him to eventually take over when pops retired.
I don't see Tommy leaving Auburn. If he didn't leave when they went behind his back to interview Petrino, he won't leave now. Lane Kiffin is a poor choice as well. I don't see him doing anything successful. anywhere. I'm afraid someone like Kippy Brown will be hired (please God, i hope Hamilton stays away from the UT family). I just don't think there is a Bruce Pearl of college football out there at this point for Hammy to consider. And naturally, thats what everyone expects (someone to come right in and change things around their first season). The only coach thats poised to leave their current program for another, that could come here and post a winning season their first season, is Steve Spurrier.
