At Auburn, rivalries sort of define the game.
The Iron Bowl. Auburn and Alabama.
The Deep South’s Oldest Rivalry. Auburn and Georgia.
These are the games that mean the most, and for good reason. Win, and the following year is relatively peaceful. Lose, and find yourself the subject of ridicule by fans dressed in some sort of reddish hue.
Aside from those games, ask an Auburn fan about rivalries, and you’ll probably get several different answers. For the younger crowd, Auburn and LSU is probably next, since that game has meant so much this millennium.
