re: 4 not enough?

While there will never be a perfect system. I do believe if they are going to increase from the current system to do more than 4 teams. My personal opinion is that it should be 12 teams. Top 8 conference champs(no automatics, but maybe based on the BCS or something) and 4 At-large bids. Top 4 conference champs get a bye, and play all games at the higher seeded teams home field till the championship game. Winning your conference and being highly ranked still means something, but it still allows great teams that may of had one bad game a chance to prove on the field they are the best.
