re: Not trying to jinx this, but if LSU somehow beats Ole Miss, Do we get game day again

That seems VERY unlikely. Assuming Georgia beats Florida, the Tennessee v Georgia game will be a top 3 or 4 (depending upon Tennessee's rank) matchup. Plus, Gameday hasn't been to Athens yet this year. Even if Georgia loses to Florida, that would still be a top 10 game. ESPN isn't passing that up.

And for those who say "But the game is (likely) on CBS!" Gameday has already gone to three sites this year (Alabama @ Texas, Florida @ Tennessee, Alabama @ Tennessee) that weren't broadcast on ABC/ESPN. They clearly have no issue with that.

If gameday appearing appearing at the LSU v Alabama game is a big deal in your decision, I would make the decision now. They aren't coming to Baton Rouge. Of course, that still doesn't mean a top 20ish LSU v top 10 Alabama wouldn't be a big game.
