I don't like or dislike name-tags. I like/dislike teams based on players, coaches, and past games. I'll only talk about football here, since that's the professional sport which matters most.

My favorite teams are (respectively): Pittsburgh, Oakland, San Diego. I won't go into why, since that's for another thread. I used to like San Fransisco, because Steve Young and Jerry Rice were my favorite NFL players ever, but they've been gone from SF for a long time, and I can only continue to like a team solely based on a former player for so long. I also absolutely LOVED Miami for exactly one day last year. You can guess which day that was when you see what team tops my next list.

My least favorite teams are (respectively):

1. New England Patriots. Man, I hate the Patriots. Why, you ask? Because they didn't deserve their first Super Bowl win. Why? Because the so-called "tuck rule" is the most disgraceful thing ever made up by a ref. I was indifferent to New England before I saw that horrible call hand New England the win at the end of the game. I will probably continue to hate the Patriots until all the main players are gone, so it'll be a while.

2. Minnesota Vikings. Tice is an asshole, and I despised Moss when he played there. I hate them slightly less now, since Moss left and they're doing horribly as they deserve. I sort of chuckle and move on.

EDIT: Ok, I'll talk basketball too, which is the only other sport I really watch.

Likes: Dallas Mavericks, Phoenix Suns. Both for the exact same reason: very entertaining to watch. <3 Dirk Nowitzki, Steve Nash, etc.

Dislikes: Detroit. That's about it.
