Doesn't happen so much. The NFL is 4th in my sports pecking order, and I've pulled for the Broncos since I was 7 when I won one of those Super Bowl squares my dad bought me. Thought I was rich at the time. And ever since Mike Vick was sent to the pokey, I've pulled for the Falcons any time they're not playing Denver.
The Braves and Georgia are my two biggest loves, and I doubt you'll find any two team combo fan that has been more tortured.
Uh, hello. Texas Rangers and Aggies!
