This is exactly why the 4, "best" teams in the playoffs is a joke. If your conference has depth, your champion has a shot of one or two losses. While Clemson proved they belong in the semis, the rest of the ACC is weak. The Big 10 has a perceived strength, but I don't really see it.
That's why there should be an 8-team playoff with the 5 P5 conference champs, the highest rated G5 champs, and 2 at-large teams.
