I believe this is who would have made the 14 team playoff from the 2023 season based on the week 15 CFP ranking and assuming this was the 2026 season with an expansion to 14 teams.
ACC - FSU & Louisville
B1G - Michigan, Washington, Ohio State
Big XII - Oklahoma State & Arizona
SEC - Texas, Alabama, Georgia
G5 - Liberty
At Large - Oregon (B1G), Missouri (SEC), Penn State (B1G)
A couple of things stand out as to why this proposal isn't in the best interest of the CFP; 1)Both Big XII qualifiers were ranked 14 or lower, and Oklahoma State has 4 loses (1 being in the Big XII Championship), and 2) one of the P2 (the SEC), missed out on having another team being in the playoff by giving the ACC & Big XII 2 auto bids.
