I have had a hard time lately picking my favorite teams, since we don't really have anything (professional-wise) all that close to us here in Nebraska.
NCAA Football - Nebraska Cornhuskers, of course. Its part of life here. Hard to explain if you don't live here I guess, but we don't have anything else for sports really. We just love our Huskers....and I'm one of the fans that supports them, win or lose.
NCAA Basketball - North Carolina Tar Heels. I've been a fan since I was in junior high or so, and have always liked them. Finally back on track this year a little after a couple of down years.
NBA - My favorite sport, used to be a big Bulls fan (even a couple years before they won any championships...I just can't follow them anymore now, after all the dismantling they did with those great teams. I've really been wanting to find an NBA team to stick with, it becomes harder when players don't stay with teams quite as much anymore. I followed the Wizards when Mike was there, but don't care as much now. I kind of like Sacto, Minny, Cleveland, Denver, Milwaukee, Seattle, and Dallas though (lots of them, I know, probably even more if I'd think about it
). I've been thinking about just following one of the closest teams to us (Denver, Minnesota, or Chicago are about as close as it gets I suppose). I don't know, right now...I've just had favorite "players", but it would be nice to have a team again
NFL - Used to be a big Raiders fan (in the Bo Jackson/Marcus Allen days), but not that big of a fan anymore. I don't know that I especially have a favorite, I don't have a problem with most teams (although for some reason I just don't like the 49ers or the Chiefs, can't really explain why other than the fact I didn't like them when I was younger) I do like to go for all the former Husker players (I'm a big Ahman Green fan, have even seen him in person a couple of times...but just not a huge Packers fan).
MLB - I'm not a big baseball person anymore, I used to be big into the Royals, and then to a lesser extent the White Sox (when Bo went there). Now, neither one really...Royals are still alright, and I find myself going for the Twins more so than anyone else now (my wife's a Twins fan as well).
Olympics - Team USA, any sport, although I really enjoy watching the basketball competition the most.
