From my understanding, Kiffin to UF would be a long shot because of portal issues.
Assuming they don’t implode, Ole Miss has a chance to be in the playoffs.
There will be a one time portal this year before the playoffs begin, so if they fire Napier at UF, a bunch of the roster will jump in the portal, and a coach in the playoffs would be very unlikely to leave his team during the playoffs. So, if hired, he would inherit a depleted roster and no portal; he would only have the spring to recruit and then pick up JUCO and Grad students.
Logistically, it doesn’t work with Kiff
