I really got into college football this past season, and I have to say I enjoy it much more than the NFL (other than the Bills). Gambling on it is very fun too.
On a Saturday you literally can have games on from noon to 3AM if Hawaii is home. There are so many different cultures and traditions around so many programs.
Its also refreshing that Im not so invested into a team like I am with the Bills, Sabres, etc. There are a number of programs I really like (Buffalo, Oklahoma, Oregon St, Boise State, Auburn), and a number I will never root for (USC, Miami, Michigan, Florida, Tennessee). It will give me the freedom too to "switch teams" and root for whoever is interesting and maybe poised to make a run.
I really think that if the NCAA went to a 16 team playoff, it would end up having gargantuan interest.... like as much as some of the pro sports combined.
