AFC and NFC Top Seed Scenarios Still in Play
| Team | Record | No. 1 Seed Odds | Key Scenario |
| Denver Broncos | 13-3 | 82% | Win or Pats/Jags losses |
| New England Patriots | 13-3 | 15% | Win and Broncos loss |
| Jacksonville Jaguars | 12-4 | 3% | Win plus two losses |
| Seattle Seahawks | 13-3 | 54% | Beat 49ers Saturday night |
The Denver Broncos remain the favorite at 82 percent odds to land the AFC’s coveted No. 1 seed. However, the New England Patriots at 13-3 are charging with 15 percent probability, and any combination of upsets could reshape the hierarchy. The Jacksonville Jaguars possess the widest range of potential outcomes, capable of reaching anywhere from the first seed to seventh seed depending on multiple games.
In the NFC, the Seahawks lead the charge at 54 percent while the 49ers sit at 46 percent. This tightly contested race means Saturday’s primetime matchup will define the entire NFC’s playoff bracket.
Division Races and Wild-Card Drama Unfold
The Carolina Panthers (8-8) look to clinch the NFC South against the Tampa Bay Buccaneers (7-9) in Saturday’s early window at 4:30 p.m. ET. Carolina holds a 76 percent probability of winning the division even with potential complications involving the Atlanta Falcons.
Wild-card positioning remains fluid across both conferences. The Houston Texans (11-5) sit at 68 percent odds to claim the AFC’s No. 5 seed, while the Los Angeles Chargers and Buffalo Bills battle for positioning with backup quarterbacks and resting starters. The Los Angeles Rams (11-5) and 49ers could both slip to lower seeds depending on other results.
