Well I like Obama but I wasn't happy to see that he supports a playoff in college football.
As I've said before (and before), the problem with a playoff is figuring out how many teams to invite. Playoff proponents gloss over this question, but it's actually enormously important. Just check out the comments here. People argue for six teams, eight teams, twelve teams, sixteen teams, etc.
Until playoff proponents can give a rational argument for a certain number of teams, there's no reason to discuss a playoff.
Case in point: 2005. Texas and USC were undefeated and they met for a (fantastic) national championship game. Should they have been forced to play Penn State and Oregon, each of which lost a game earlier, before playing each other? No!
