Would obviously prefer to get someone like Petersen, Patterson, Gruden, or Kelly... but I'm not sure any of those are realistic. Brohm leads the 2nd tier for me.
From all the stuff I see and hear this is what I can put together.
Petersen - LOVES the Pacific Northwest, happy, content, makes enough money. Not coming.
Patterson - Texas guy, has a great thing going, money doesn't talk. Not coming.
Gruden- got a great gig, makes plenty of cash, has said many times he doesn't like NCAA rules. Nope.
Kelly- watching college football for best fit for him. Possible, but more likely UCLA if they as expected dump Mora.
If TN and UCLA are both open we lose.
Brohm- Very possible, believes he can make the jump, has a good offensive mind, winning now, knows the conference.
Arkansas might make a run at him but Tn would have a better chance to land.
Petrino- ready, willing and able if Tn calls, but not convinced here UT will do so with his past.
Another possibility is Jones and UT work out a compromise for less money, Jones could slide to Ole Miss at reduced salary. Jones would receive a long contract and rebuild Ole Miss and clean it up there. Wouldn't win 10 but at Ole Miss who does? 8-9 wins there would be acceptable.
Now, these are summaries of a lot of things, read, surmised, discussed, and a lot of them intersect from different places, which makes one wonder. TN does have a better situation now than when Jones came and that does make a difference. Jones can be appreciated for putting us back into the category of good jobs, if the administration doesn't let it regress. And that, is the rub.
