I worked for the UF Athletic Assoc. for 4 years while he was there, was around him frequently and noticed several consistencies about his personalty:
He is extremely loyal to his alma mater. I am not saying he wouldn't coach college ball again, but he will never and I MEAN EVER coach for a SEC team. All the talk about UT, Miss St. is complete BS, ridiculous and without the slightest basis. The man loathes Tenn (not as much as UGa, but definately 2nd place).
He is an ego maniac. He would only go to a program that has the APPEARENCE of being washed up, but still big time.He would not go to a program that wouldn't have the fan base, alumni support, etc. to deliver a top notch program. Although he may seem to the public to be the one to turn a program around, he wouldn't take on one without the infastructure in place.
He is a fanatical golfer. The man plays at least 5 rounds a week, even during the season. You think he's going to get that quality of golf in knoxville or starkville? Please. There's no ponta vedra in either of those towns. It sounds silly, but its a huge deal to him.
That being said, he may end up somewhere in the PAC-10. If he stays in the NFL the ONLY place you would see him in the next 2 years is Jacksonville. Del Rio is crapping the bed, Jax absolutely loves him and he has a home on one of the Ponta Vedra courses.
