He makes $9 mill now at OM so that’s not really a lucrative. Deal especially since OM is gonna match anyone. I think Bama, LSU, Miami and Texas are about the only ones he would leave for.
Correct, but Florida is also pretty well respected from a sports standpoint. "Only" a $2M raise, something over 20%.

Maybe Florida needs to sweeten the deal, offer him 13 or 14, not mention better weather, especially in the winter, a larger town but not huge, a more storied program, etc. Admittedly, though - Kiffin has sort of a similar personality as OM's students and supporters.
Remember - both Dan and his wife allegedly loved Starkville, but wouldn't take a substantial raise to stay, and left at the drop of a hat. So you really never know what Kiffin will do.
