Georgia is the same day as Florida/LSU and Alabama/Ole Miss, so it's already been slotted as probably a noon game. Auburn is the same day as Georgia/LSU. The Alabama game has a decent shot at being on CBS, but if depending on what's happening, Arkansas/Ole Miss or LSU/Auburn might conceivably look more interesting. Ole Miss is the same day as Florida/Spurrier and Georgia/Auburn.
I think we'll be on CBS twice this year (UF and Bama), but if we're 3-3 or 2-4 after UGA and Alabama's lost a couple of times, we might not even get that.
And as to the OP's question: Gameplan is a must-have, especially if you're a Tennessee fan who lives out of state. In the five or six years I've been getting it, I think there's only been one game (vs LA-Lafayette a couple of years ago, I think) that hasn't been available at all. And it's great for watching other games too. Well worth it, IMO.
