It wouldn't matter. CBS was the network the Alabama/South Carolina game was on, and Gameday was still there. They went to BYU/TCU last year if I'm not mistaken, and if my memory serves me correctly that game wasn't even nationally televised. I think it was on the Mtn. or Versus.
The Steve Spurrier storyline is a good one, but don't forget the winner of the game between SC and Florida goes to the SEC Championship (assuming Florida wins this weekend vs. Vandy). And since I don't think Gameday has been at UF this year, I see that as a more probable location.
