College Football Playoff Format at a Crossroads: SEC and Big Ten Disagreement Could Stall Expansion

As college football barrels toward another transformative era, the future of the College Football Playoff (CFP) remains uncertain. At the heart of the debate are two powerhouse conferences—the SEC and Big Ten—whose inability to agree on a new format could freeze the playoff at its current 12-team structure.
The Stakes: A New CFP Era Begins in 2026
The original 12-year CFP contract with ESPN ends after the 2025 season. A new six-year extension begins in 2026, and many expected it to usher in an expanded playoff. However, a memorandum signed by all 10 FBS conferences and Notre Dame gives the SEC and Big Ten significant influence over the format. Without their consensus, change may be stalled.
Competing Visions: 4-4-2-2-1 vs. 5+11
Two competing models have emerged:
- 4-4-2-2-1 Format: Proposed by the Big Ten, this model gives four automatic bids each to the SEC and Big Ten, two to the ACC and Big 12, one to the highest-ranked Group of Five champion, and three at-large bids.
- 5+11 Format: Favored by the SEC, this model offers five automatic bids to conference champions and 11 at-large selections, emphasizing merit over conference affiliation.
The SEC’s shift toward the 5+11 model came after internal pushback from coaches during spring meetings. Big Ten officials argue that the SEC’s eight-game conference schedule (compared to the Big Ten’s nine) gives it an unfair advantage in an at-large-heavy system.
Selection Criteria Under Review
To address concerns about fairness, the CFP committee is revising its selection metrics:
- Strength of Schedule: Will now weigh games against top 30–40 programs more heavily.
- Strength of Record: A new metric that rewards quality wins and reduces penalties for losses against top-ranked teams.
These changes aim to level the playing field, but whether they’ll be enough to sway SEC officials toward a nine-game conference schedule remains to be seen.
What Happens Next?
The deadline for a decision is December 1, 2025, set by ESPN executives. If no agreement is reached, the playoff will likely remain at 12 teams for the foreseeable future.
SEC Commissioner Greg Sankey remains firm: “That can stay if we don’t agree.” Meanwhile, Big Ten Commissioner Tony Petitti continues to advocate for a format that incentivizes tougher non-conference matchups and reduces subjectivity in selection.
