According to some agents, Kiffin was indeed offered this week and had even agreed in principle. Sexton was (still is?) getting all the little details finalized. I'm still not certain that Kiffin has fully backed out... mostly because of who all is reporting it right now, and who isn't.
On Freeze, the same people say he absolutely wants it and has some heavy backers at auburn, but also some heavy detractors including on the University side. If they go that route, a classic auburn power struggle likely ensues. He does seem to at least have the backing of most fans which certainly helps the "let's hire him!" side. Personally, I hope they look elsewhere or a deal falls through.
The best value bet has always been Grimes. Hope it still happens. Earlier this season when things really started to unravel, there was a push to try and line him up as HC with Muschamp as DC by some boosters.
