College games are just more exciting.
There's an intangible "feel" to the college game that I don't get watching NFL games. The NFL seems to have lost some of it's aura that I found so attractive when I was younger. It's hard to describe, but the same attraction to the pro game doesn't exist for me like it used to.
I've also gotten more into the NBA the last five or six years. I consider myself a pretty big OKC Thunder fan now.
As for the NFL, I'll watch the Rams, but that's about it. I'll watch Monday Night and Sunday Night occasionally. But I'll watch college games all day long on Saturdays.
