Four words sum it up: TOO EARLY TO TELL.

The reason the bowl system exists is not to decide the National Champion. It never has been. It is all about the almighty dollar. Teams that particiapte in bowls get money. Teams in conferences split the bowl money within the conference. The only way to get a playoff system in place is to take the money out of the bowl system. Good luck doing that.
