I'm not quite as doubtful on their ability to lure Kiffin.
First, Kiffin was willing to suck a **** last year to get the Miami job, but he was never a candidate. He may have a "revenge" motivation to take less money at F$U for the chance to show up UM and Mario.
Second, F$U will be done paying Taggart and have a supposedly reduced payout for Prison Mike Norvell.
Third, I believe that the ICs are uncapped for next year too. When you combine that with the ability of a first year coach to "waive" the prior coach's players, it would be (theoretically) possible for Kiffin to sign 85 HS, JuCo, and Portal players in his first year at F$U.
Finally, Kiffin would really be able to build a legacy for himself if he was able to restore the consistent records of the Bowden days. Say what you will, F$U has won a title under two separate coaches in our lifetimes, and Ole Miss has not.
The biggest issue that F$U would have to navigate would be the buyout of the Ole Miss contract. If they can scrape together the money for that, this might not be such a crazy plan for them to attempt. It's probably their only shot at saving the program, I don't think Neon Deion is the answer.
Have they scraped together enough money yet to fix the urinals?
