Florida will beat Alabama in the SEC championship game. Texas will win the Big 12 (I can't decide who they will beat in the conference championship game - the north isn't that impressive this year!). Florida and Texas will meet in the BCS championship game. Florida will win it all again this year.
Note: I am not a Longhorn fan... just making a prediction.
Florida will win the BCS. It will win over Alabama in the sec championship and then Texas in the BCS. Both games will be #1 vs #2.
