The games up for that day:
Alabama at Mississippi State
Tennessee at Arkansas
Auburn at Georgia (likely two top 20 teams)
Florida at South Carolina.
LSU and Mississippi play Western Kentucky and Louisiana Tech, respectively with kickoff times in the evening. Kentucky at Vandy is already set for a 12:15 kickoff on the SECNetwork.
Presumably they are waiting for the Arky/SC and Bama/LSU outcomes, although it is hard to see why. I guess you could see them picking Florida at a top 10 South Carolina for the spectacle of Spurrier possibly losing ground in the SEC East race to his old school. I don't see what they would want from the Tennessee at Arky game. As for waiting for 'Bama, having the team of the Century of the Year playing is worth something.
The TV slots remaining are 12:00, 3:30, 6:00 and 7:45. Apparently the selection order for those games is the 3:30 slot, then 7:45, then 6:00 and then 12:00 (although by the contract, CBS would have a first pick for both of their games). I think we'll end up at 3:30 if South Carolina loses this week, since it'll be for the SEC East. While CBS would love to have 'Bama, the compellingtude of two top 20 teams, the South's Oldest Rivalry, and the division title on the line wins out, in my mind. If SC wins, it is still a toss up.
Noon CBS: Florida at South Carolina
12:21 SECNetwork: Kentucky at Vandy
3:30 CBS: Auburn at Georgia (70%) or Alabama at Mississippi State (30%)
6 ESPN2 Tennessee at Arkansas
7:45 ESPN Alabama at Mississippi State (70%) or Auburn at Georgia (30%)
Either way, I don't see us kicking before 3:30, and we could get a night game (remember, set your clocks back on November 5th) at 6pm or 7:45pm. The only way we are noon is if we lose to New Mexico State and Auburn loses to Open, OR CBS is picking the Noon game before ESPN picks, which makes it even murkier. Or someone requests a noon kickoff. Whichever.
PS. If you have anything more definite on the selection order that I couldn't find, please share that in the comments.
