I idly wonder for the 5 stars out there how much of the equation is NIL.  90%?  60%?  20%?  
It's not the whole deal of course, though if one offer is $2 mil and the other is half a mil, it becomes 99%.  
Imagine say UNLV comes up big from a massive donor and can offer $2 mil to 5 stars, would many of the bite?
But let's say the offers are from the Big Boys and the NIL monies are close but not the same, is that the final factor?  I know it depends.
