Imma, don't be stupid. The expansion to 12 teams was approved by the 11 member CFP board managers back in 2022.
Here is who comprised that body at the time....tell me again how this present set of circumstances was happening without agreement from conferences outside the SEC and B1G
Members of the CFP Board of Managers are Timothy Caboni – Conference USA (President, Western Kentucky); Jim Clements – Atlantic Coast Conference (President, Clemson); Gordon Gee – Big 12 Conference (President, West Virginia); Jack Hawkins – Sun Belt Conference (President, Troy); Rev. John Jenkins – President, Notre Dame (Independent); Kristina Johnson – Big Ten Conference (President, Ohio State); Mark Keenum (chair) – Southeastern Conference (President, Mississippi State); Kirk Schulz – Pacific-12 Conference (President, Washington State); Satish Tripathi – Mid-American Conference (President, Buffalo); Gerald Turner – American Athletic Conference (President, SMU); Keith Whitfield – Mountain West Conference (President, UNLV).
