Good article by Yahoo! Sports' Charles Robinson about the major feuds around the league.
I love Bart Scott's attitude toward players on other teams:
I hate everybody on every other team than mine. I don't give a [expletive] about anybody on any other team – period. I don't speak to them during the game. I'm not high-fiving guys. And I'm talking about guys who have been here and left, too. It doesn't matter. You're trying to take something away from me that I deem important. Why should I care about you? Why should I like you? You don't have to like me, and I don't have to like you.
Ask me who I'm rooting for in the Super Bowl. If I'm not in it, I hope they cancel the damn thing.
