For me its like this...
NFL-Philly and Dallas. I despise Eagles fan, and I just don't like Dallas. I beginning to hate NY as well. Especially after last seasons final game.
NHL-Colorado. I'm a die hard Red Wings Fan. I can't stand the Avalanche, ever since Claude Lemiux took a cheap shot on Kris Draper.
NBA-Lakers and Celtics. I can't stand Kobe and I never liked the Celts. I couldn't stand Bird, McHales, Parrish, Ainge, the DJ(god rest his soul)
MLB-Yankees and Braves. I can't stand either of these 2 teams. Jeter is a whiny over rated baby and I can't stand the Braves.
NASCAR-Jeff Gordon and Jimmie Johnson. Everytime one of these 2 clowns win it makes my blood boil.
NCAA-DOOK, DOOK, DOOK. I hate Dook with a passion, Dickie V and his bandwagon jumping ass. The other ACC schools I can stand, along with the other Big 10 schools. OSU and Michigan fans are close, but not nearly as bad as the Dookies.
Hail to the Lion, Hail to the Heels!!
