Never heard an amount from anyone I would trust enough to post. All he said was it was an unprecedented package for a college coach. Logically I think that number would be high unless including every possible bonus for SEC championships, BCS bowls , etc...
If he is hired I will go out on a limb and say no way the base is over 4 to 5 million, probably between those two. Just my opinion but I think logic sides with that stance.
I am of the "it's far far from done but the pursuit is about to get official" camp and we will know something sooner rather than later at this point imo.
