re: Playoff good as is? Or need to be expanded?

It seems ironic, given Bama's dominance of college football of late, that we are talking about expanding the college playoff format. The impetus for the playoff format was the controversy in crowning a champion from the old BCS system. I'm not saying that it should not be expanded, merely pointing out the fact that it seems that lately it's been relatively easy to pick a clear #1.
