Spurrier has come out in favor of a rivalry game with new division-mate Missouri, calling it "The Battle of the Columbias". I wholeheartedly support this new rivalry, but think that it's not alone in new potential rivalry games.
aTm and LSU: The Battle for the Sheep (Trust me, you want LSU to win this one. They kill it and fry it, sometimes in that order, but it's still the more humane option.)
aTm and Bama: "The Bear is more loved here, damnit" bowl
aTm and Auburn: "No, we hate Alabama more" bowl
Mizzou and Florida: "No Really, we have academic cred!"
Mizzou and Vanderbilt: "We really wanted to be in the Big Ten, but whatever" bowl.
Mizzou and Kentucky: Meth Madness!
And of course not a new game, and not every year, but:
Georgia and Mississippi State: The Michael Vick Play-In Game (Too soon?)
