What is certain is this: if LSU doesn't totally screw up against Georgia, they are going to playing Alabama in the BCS National Championship Game.
And, if LSU loses in overtime or on the last play of the game, it's STILL likely that they'll be playing 'Bama in New Orleans, because it's highly unlikely they will drop low enough in the polls to fall out of the game. Especially if Oklahoma State wins over OU in their Big 12 finale.
The only way the Tigers could end up not playing on January 9 is if they tank big-time against Georgia, and Oklahoma State runs roughshod over Oklahoma.
