I'd say recently I've not watched much sports. I don't have the patience to watch an entire game, and to see my team lose. I'm in my early 20s, and I don't know, sports seemed so much more "innocent" during the 1990s. Here are my teams:
Hockey: Does hockey even come on T.V. anymore. I'd say it isn't too fun to watch on T.V., but NHL 94 on Sega Genesis was fun. I think in the late 90s I went to a Washington Captials game, and man, IT WAS AWESOME (eventhough I was litterally at the top row). So I guess I go for the home team, the Caps.
American Football: During the 90s I liked the Dolphins and the Redskins. Now, I watch maybe 2 or 3 games a season. I find it more fun to antagonize my sister (a huge Bears fan). Man, last season Monday night football, Bears vs. Cardinals was a fun night indeed (though, the bears still won).
Basketball: I can honestly say I've never watched a complete came of Bastetball in my life. I watched a little bit of GMU last season (that's the school I go to), but in the end I just prefer playing. I'm good at rebounds, but I am terrible on offence
Baseball: I'll turn it on if I'm having trouble sleeping, I'll be out by the first inning
Soccer: I watch soccer only 4 times a year, and that is the World Cup. For those couple of weeks, I vote for America.
Rugby: I watched the Rugby World Cup last time it was on. Didn't vote for anyone, but it is in my opinion a better sport than American football.
MMA: A couple of years ago, I really was into MMA. Recently, I've become fed up with it all (I think the "golden years" of one style vs. another is past. I'll watch the old fights [which don't have rules], but now...I don't know, just lost my taste for it all). But, I still like the Russian Heavy Weight Fedor Emelyanenko.
