NHL-Devils. If anyone dares to call out Stars, I'm going to have to show them who's boss.
NFL-Now, at the beginning of the season, I watched that some ESPN crew played a season of Madden 2002, on which they had the Bucaneers beat out the Bills in the Super Bowl. Now, they were half right, but I went along with that bet. So if anyone says that I just like winners, it wasn't because they won, I liked them from the start of the season. I've just given up on the Seahawks going anywhere.
MLB-I've given up on baseball. It just seems so ludicrous that it's getting later and later. I wish they could have some afternoon games, or something that I could watch when I get home. But if I had to pick, it would the Red Sox. Or the Mets. Or the Rockies. Depends on what day it is. Usually by August I'm done with the Mets, though. Except in 2000....
NBA-I don't like basketball, but I'll go with the Timberwolves.
International Soccer-Norway, Denmark, France, or pretty much anyone not the US. Yeah, I'm from the US, but I get to see a US team win enough in baseball, football, etc(unless a Canadian team, but I'm fine with that too). So it's always nice to see another country win.
NCAA-UConn. I've also taken a liking to any Kentucky, Arizona, Colorado, Utah, and Vermont teams. Probably just because they're my favorite states. Don't want to get into that now, though. And of course, I haven't been to college yet, so I don't have an alma mater to root for.
Olympics-depends on the sport, but I usually pick Norway or France for Winter Olympics, and the US or Australia for Summer. Unless there's some other reason to pick someone else.
Golf-Mickelson, Olazabal, and Garcia.
Don't really care about tennis, and can't think of anything else right now....
