Total homer - Wings, Pistons, Tigers, Wolverines, all from childhood. I've given up on the Lions pending new management and/or ownership, so I'm not really an NFL fan right now. Like steelergirl, I was a big NASCAR fan, until the Bettman-esque stupidity of late, but I never was a big fan of one driver or team...

Outside those teams, I've found myself following individuals rather than teams. When I was growing up, I had deep hatred for anyone that played for my teams' rivals, so I didn't pay attention to the careers of the likes of Jordan, Payton, Roenick, Bird, Magic, or even Favre as much as I could, and I don't want to miss the best parts of the new guys' highlights...
