I love watching college football, but hate watching pro now. Watching the pro game, you can see who is throwing it because of deals on the side and whatnot. And even with college, it's really hard for me to enjoy the NCAA BCS games, because there's a shit ton of money involved in those. Smaller schools are fun to watch, and they're highly underrated.
As far as playing sports goes, weightlifting it is, bu tthat's more for self-improvement than anything else.
