Latest News
Week 14 reshuffled the deck. The 49ers' 28-16 win over the Seahawks was their fifth straight, and they now lead the NFC West by two games. Meanwhile, the Eagles survived a scare against the Giants, winning 34-31 in overtime, but quarterback Jalen Hurts aggravated a knee injury. The Cowboys crushed the Eagles' division rivals, the Commanders, 45-10, and have won four of five. The Chiefs edged the Bills 20-17 in a defensive slugfest, but Patrick Mahomes played through an ankle injury.
In the AFC, the Ravens (13% probability) and Dolphins (10%) remain contenders, but both have tough schedules ahead. The Bills (8%) have lost three of four and are now on the outside looking in.
Key Facts
- Chiefs (22%): Mahomes' ankle is a concern, but Kansas City's defense ranks 5th in DVOA. Their remaining schedule includes the Patriots, Raiders, and Bengals—two of which are winnable.
- 49ers (18%): Brock Purdy leads the NFL in passer rating (118.8), and the defense is 1st in DVOA. They face the Cardinals, Ravens, and Commanders—only the Ravens pose a serious threat.
- Eagles (15%): Hurts' knee is the biggest variable. If he's healthy, Philadelphia's offense is elite, but the defense has slipped to 15th in DVOA. Remaining schedule: Seahawks, Giants, Cardinals.
- Cowboys (12%): Dallas leads the NFL in point differential (+198). Their defense is 3rd in DVOA, but they must face the Bills, Dolphins, and Commanders—a tough stretch.
Analysis
Our model uses a Monte Carlo simulation with 10,000 iterations, incorporating weekly Elo ratings, strength of schedule, injury probabilities, and playoff seeding scenarios. The Chiefs' path to the Super Bowl remains the clearest: they are on pace for the AFC's No. 1 seed, which comes with a bye and home-field advantage. However, Mahomes' ankle injury reduces their offensive efficiency by an estimated 5% based on historical QB injury data.
The 49ers are the most complete team in the NFC. Their defense is dominant, and Purdy's efficiency is historically good. The main risk is that they may have to win three playoff games on the road if they don't secure the No. 1 seed. Currently, they are tied with the Eagles for the conference's best record at 10-3, but Philadelphia holds the tiebreaker.
The Eagles and Cowboys are both vulnerable. Philadelphia's defense has been gashed by good offenses (49ers, Cowboys, Bills), and Hurts' injury could limit their explosiveness. Dallas is hot but has a brutal remaining schedule; they could easily finish 10-7 and miss the playoffs entirely if they stumble.
Prediction
Our model projects the Chiefs to win the AFC Championship with 35% probability, followed by the Ravens (20%) and Dolphins (15%). In the NFC, the 49ers are favored to win the conference at 32%, with the Eagles at 28% and Cowboys at 18%. The Super Bowl matchup most likely is Chiefs vs. 49ers (22% implied probability), followed by Chiefs vs. Eagles (18%) and 49ers vs. Ravens (12%).
We expect the Chiefs to hold steady as the betting favorite, but the 49ers' odds will continue to rise if they beat the Ravens in Week 16. The Eagles' odds could drop if Hurts misses time. The Cowboys are a dark horse: if they win out, they could leapfrog both the Eagles and 49ers for the NFC's top seed.

Bull Case (Optimistic)
If the Chiefs get a fully healthy Mahomes and secure the No. 1 seed, their Super Bowl probability could rise to 28%. The 49ers could hit 25% if they win out and the Eagles lose one more game, giving San Francisco home-field advantage throughout the NFC playoffs.
Base Case (Most Likely)
Chiefs at 22% and 49ers at 18% represent our central estimate. The Eagles hover at 15%, and the Cowboys at 12%. The Ravens and Dolphins are long shots at 13% and 10% respectively. This scenario assumes no major injuries to key quarterbacks.
Bear Case (Pessimistic)
If Mahomes' ankle limits him and the Chiefs lose the No. 1 seed to the Ravens, Kansas City's probability could drop to 15%. Similarly, if Purdy regresses and the 49ers lose to the Ravens, their odds could fall to 12%. In this case, the Eagles (18%) and Cowboys (16%) would become co-favorites.
