Association football (soccer): I'm not really passionate about one team, but I like Arsenal.
MLB: I dunno, the Cardinals, I guess. I don't watch that much baseball - it's on very late in the UK.
NBA: Chicago Bulls, only because Luol Deng played for them when I first was watching the NBA. I don't care that much, though.
NHL: Literally no opinion.
NFL: Indianapolis Colts. This is the one sports team that I really care about. I've been a dyed-in-the-wool Colts fan since I started watching in 2002.
Tennis: Novak Djokovic is my main man, and Agnieszka Radwanska is my favourite women's player.
