Cleveland Browns of course.
Baltimore Ravens (Byproduct of the Browns).
Any Chevrolet/GM product (I'm more a ford man myself).
Jeff Freakin' Gordon... What a putz.
NHL (My favoritist bestest sport on Earth ever, and the only one I played extensively):
Philly Flyers (though I want them to win their current Series).
Detroit to an extent.
Colorado to an extent.
I'd love for Boston to go all the way this year personally... I root for the Penguins in any other situation, but since there was no way in hell we were making the playoffs and we're doing serious rebuilding/restructuring, I'm gonna wish for some good things for normally crap teams. Boston's my first fave... I almost wouldn't mind seeing Philly though, as they have gone too long without. I like Jersey too.
Out west I like the Kings a lot... That and maybe the Stars, but not much else. West is just not as competitive I think, and a weaker conference that is riding the playoff wave a few teams have created. Much more competitive in the East I feel, and that hurts all Eastern teams in the playoffs and even in their race for the playoffs.
