How to become a fan of college football.

[Golden_Rhino]

I have been a casual fan of college football for most of my adult life. I enjoy watching the games when I can, and find them to be a lot of fun to watch, but I don't know much about the programs, or the players. I understand what I am seeing on the field, but little much else.

I can keep track of NFL teams because there are not too many of them, and for the most part, any turnover on a team comes from the draft, or known players switching teams.

What I wanna know is how do you hardcore fans stay on top of everything? There are over 100 teams, which change over ~25% of their rosters every year, and their replacements are pretty much unknowns. How can I make the jump from casual fan to knowledgeable one?
