Again, 4 doesn't work because it omits conference champions AND adds too much of the human element.
So we're going to make conference championships more meaningful by adding three non-champions to the playoff?
And an 8-team playoff only increases the "human element." It's pretty easy to decide the top 4 teams. It's a lot harder when you're talking about the 5th, 6th, 7th and 8th ranked teams.
If you really cared about those things, the only option would be a six-team playoff with five Power 5 champions and the highest ranked Group of 5 champion. That would be better than an 8-team playoff, but still too much.
Does anybody actually think this year's playoffs are worse without Penn State? That's what we're upset about? There's nothing to fix. The system works. The past two years have been exciting as ****, and this one should be no different. Keep it the way it is.
