Pate had a pod I saw yesterday talking about the 4-4-2-2 format. He generally doesn't want playoff expansion, but he did note that if you do go to 14 or 16, then he actually liked the auto bids, but only if the P2 added what amount to play-in games during CCG week.
So the P2 would have their 1-2 play a CCG but each would get 1 of the 4 conference autobids. But then the 3-6 and 4-5 place teams would also play (at the 3/4 seed field) and the winners would get the remaining 2 autobids. His argument is that is 2 more really good FB games to enjoy, and less arguing about who gets picked - your record gets you to 3/4/5/6 and then you gotta win a game. Essentially, its a play in game and you've expanded the playoffs even more lol.
The ACC and Big12 with only 2 autobids doesn't fit as well. No additional CCG really needed. Maybe you'd make the regular season champ the conf champ, and have 2-3 play for the 2nd bid? IDK. He didn't have much for that. He was more focused on the P2 of course.
Honestly, I don't think any of this CFP format stuff matters much in the face of all the other problems (money, NIL, unlimited free agency, tampering, et al) facing CFB.
