I suppose I slightly prefer professional when it comes to football. I'll generally only watch Oklahoma and Alabama play in college football and usually don't care about any other games (except in a few cases). In professional football, I pay the most attention to the Broncos and Cowboys (*sob*), but will also watch other teams play provided it looks like it'll be an interesting match. Games like tonight's, however, I won't bother wasting the money for the electricity to power the TV...
And then I just don't really care about any other sport.
