Since it's speculation, let me throw this "possibility" in. May have been posted already, I heard it on sportstalk a couple of days ago, when everyone was talking about possibilities.
If Tennessee and Auburn won out, they could play each other in the BCS title game, without even making it to the SEC title game.
I know that it would never happen, with all the help needed, but think what a mess the BCS would have. It would take the teams above them losing, and a couple of huge upsets, but Arkansas could beat UF in the SEC title game. And to really give you something to ponder on, if this happened, the SEC champ could not go to a BCS bowl, because the #1 and #2 would be playing each other, and no conference can send more than 2 schools to the BCS.
Personally, I would love it, just to see more chaos in the BCS. They already have the 5th game in place. Time for a 4 team playoff.
