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

I've changed my mind almost every year on whether it should be 4 or 8. Sometimes both make sense given a particular season. I do wish they would eliminate the committee as the single determining factor though. I think using a formula like the old BCS to rank the teams where the committee poll is a variable in it would be the way to go. When I hear terms like "eye test" it just makes me eye roll.
