I've always been a pretty decent BCS supporter, but I've begun to get on the bandwagon for a 4-team playoff and MAYBE....MAYBE an 8 team.
While the idea of every conference champion goes into the tourney is kinda cool, you would have pretty big teams playing some pretty meaningless games. Plus, it's harder to filter those games through the current Bowl system. 4 team and even to an extent 8 team allows you to maintain some of the same bowls, while also have a pseudo-playoff system going.
