Well I'm not sure the allegiance will completely fade but I love college football enough to share some of my crazieness.
As for the hatred of Bama, I think it's probably a combination of things. The Bear thing I could kind of understand and it was long before my time. But during the Franchione courtship there were tons of fans from Tusca-loser-ville who downgraded our school and our program and
could not believe that anyone would ever actually leave Bama on their own terms. They couldn't fathom the fact that our current facilities, program without sanctions, ect., were enough to entice someone to leave their great program with their X amount of championships from the stone-age.
So "The Third Saturday in October" has become a tradition in my house. I even throw on an orange Vols shirt, which I must say, is a much better looking orange than that burnt crap TU wears.
