UGA and UF are having "discussions" about the WLOCP apparently, though this happens fairly often. Both home stadia are larger in capacity than the one in J-ville.
I'm pretty sure the NS games in ATL or Big D pay a lot more to the team that plays than they earn at home, but the local merchants of course don't.
My guess is the primary job of any AD is to raise as much money as possible. It would be interesting to see a typical breakdown of income:
Ticket sales
Donations
TV
League portions
Booze and food concessions
Whatever else.
I guess the TV thing is dominant.
