As with previous years, I still say that if you support a playoff in college football, you need to decide how many teams to invite. 4? 6? 8? 12? 16?
The problem is that every year the "right" number of teams is different. So in keeping with previous years, lets look at how many teams you would put in a playoff this year (for instance, last year, Ohio State deserved to play the final game against one of 8 other teams that had a case).
This year, how many teams? Eight teams indisputably deserve to be in a playoff, which is to say there's no way to choose between them. Boise State, which went undefeated, would at least have an argument. Here's the updated chart:
This year doesn't help those who advocate for a playoff. If you're going to have a playoff to be "fair", you must invite at least eight teams. The whole idea just doesn't work.
