According to this report by Phillip Marshall, Auburn's offer to Muschamp is in the $1.5 million range. Message board rumors had placed it around at least $1.2 million after the initial reporting this morning.
Auburn does have a precedent of paying over $1 million for a coordinator. Gus Malzahn was paid $1.3 million while at Auburn. Muschamp's offer was always going to be over $1 million.
As for a timeline... still no word. We could know something this afternoon, or it could stretch into next week.
Honestly, I'm feeling fairly good about this situation right now. I have absolutely no concrete reason to feel that way, but as I said in the earlier update, I don't think it will come down to the amount of money he's offered. I think it comes down to the right fit for what he's looking for. We know he loves Auburn. He knows Auburn loves him.
