College Football Playoff: The mathematical split in the field after Week 9
New tier analysis suggests Miami has nearly locked its spot, while a chaotic bottom tier will likely shed multiple teams by next week.

The College Football Playoff race has fractured into distinct probability tiers following a volatile Week 9. While the top of the field remains stable, the middle and bottom sections face immediate elimination threats as the season enters its decisive month.
Miami enters the rankings with a 98.3% average chance of making the playoff. The Hurricanes won a tight game against North Carolina, recovering a fumble and driving for a touchdown to secure the lead. Despite allowing 31 points per game over the last three weeks, their offensive output is high enough that they are projected to finish 10-2. They would need to lose to Notre Dame and two other home games to miss the cut, a scenario SP+ rates at only 1%.
The second tier consists of Indiana, Notre Dame, Utah, and Georgia. These four teams hold between 84.7% and 89.2% playoff odds. Indiana faces a quarterback crisis with Josh Hoover completing just 16 of 37 passes in his last two games. Utah dominated Cincinnati, leading 42-6 at halftime, while Georgia must stop fumbling the ball. They have committed 15 turnovers this season, a weakness that cost them the game against Auburn.
Ohio State, UCLA, and Wake Forest form the third tier with roughly 65% to 71% odds. Ohio State is the most vulnerable among these blue bloods. After losing quarterback Julian Sayin, the Buckeyes relied on freshman Luke Fahey but settled for field goals against USC. They face five straight top-30 opponents in SP+ rankings over the final five games. Wake Forest, meanwhile, has beaten its projections for seven straight weeks, averaging a 47-8 margin of victory in its last four games.
The fourth tier contains seven teams, including Texas Tech, BYU, Alabama, and Texas. All seven are virtually guaranteed a bid if they win out, but none has a greater than 31% chance of doing so. BYU holds the strongest position in this group due to a quality win over Notre Dame. This win acts as a mulligan, giving the Cougars a 62% chance of finishing 10-2 or better.
The bottom tier includes ten teams that will likely produce a single playoff bid. Iowa visits Northwestern in a direct eliminator, while Tennessee faces Kentucky and Missouri faces Texas. Florida and Oregon both sit at 5-3. The G6 group saw James Madison eliminated after an overtime loss to Troy, leaving Boise State and New Mexico as the primary contenders for the guaranteed spot.
