re: Iron Bowl is biggest rivalry in the South?

It depends on your definition of rivalry is. If it's current ranking of the two teams or the competiveness of the game then obviously it's not right now, bama has been horrible lately. I personally think you have to measure the history, intensity and what it means to the two schools...any other measure fluctuates to much from year to year. If that is the case then I don’t see how any other rivalry in the South could be ranked ahead of the iron bowl.
