Something's going to change and we'll likely see an expanded playoff, for two reasons. First, there'd be a poop ton of money involved, and these decisions are always driven by moolah. And secondly, the playoff has wrecked the other bowl games - or at least diminished their importance to the point of irrelevancy.
I don't know what the answer is, but whatever these d!psh!ts do, it had better not dilute the importance of the regular season. One of the beautiful aspects of college football is the outsized importance the regular season has with regard to determining a team's season. Even losing one game can dash hopes. There is a tension, even early on, like when we play the Chuggers, and there is some beauty in that. Compare that to the NCAA hoops tourney where you can finish 7th in your conference and still make it in. Dreadful.
I think we'll see some version of all the P5 champs making a playoff, plus one G5 then maybe two wildcards for an 8 team playoff. While I am leery on the surface, I'd be willing to give this a whirl. I'd also like to see a return to computer rankings determining the field. The committee is biased and they really spit the bit this year by picking the Bucknuts over aTm.
How this would resuscitate the other bowls, I have no idea.
