In order of what I would want to watch: College football>>>>>Rockets>>>Astros>Texans. I can only watch my teams in the professional level. I can watch almost any D1 college football game.
I don't watch random NBA games, just the Rockets. The NFL I'll watch some random games every now and then. But CFB, I'll watch a random game or flip through them back and forth if I'm in front of a tv on Saturdays.
I didn't really start following CFB until after I graduated from UH. Granted, the team was terrible while I was student, but friends got me to start coming out to games and had a great time. I'm still more of an NFL fan than college, but I do enjoy watching both even if I have no reason to root for either team playing.
