The 2026 NFL Divisional Round has arrived, and it carries the weight of a league in transition. After a Wild Card Weekend that saw four game-winning touchdowns in the final three minutes—the most in postseason history—the “expect the unexpected” mantra has never been more relevant. Familiar dynasties like the Chiefs and Eagles have fallen, leaving a field where four of the remaining eight quarterbacks have less than three years of experience.
In this high-stakes landscape, the line between a “favorite” and an “underdog” has blurred. From the thin air of Mile High to the sub-zero wind chills of Soldier Field, the potential for chaos is immense. Here is a ranking of the four Divisional Round matchups based on their Upset Potential, from “Business as Usual” to “Total Mayhem.”
4. San Francisco 49ers at Seattle Seahawks
Upset Potential: Low
The Line: Seahawks -7
The largest spread of the weekend belongs to the NFC West showdown in Seattle. The top-seeded Seahawks have been the most consistent team in football this season, boasting the league’s No. 1 scoring defense and a breakout MVP candidate in Jaxon Smith-Njigba.1 Under Mike Macdonald, the Seahawks have transformed Lumen Field back into a fortress, recently dismantling three playoff teams in three weeks.2
Why an upset is unlikely:
The Seahawks handled the 49ers during the regular season, and Seattle’s defense matches up perfectly with Kyle Shanahan’s scheme. San Francisco is battling significant injuries, and while Brock Purdy is a proven winner, asking him to navigate the “12s” while under constant duress from a dominant Seattle front is a tall order.
The “What If”:
For the 49ers to pull off the +275 moneyline shocker, they need a vintage performance from Christian McCaffrey to keep the clock moving and Sam Darnold (the Seahawks’ resurgent QB) to revert to his “seeing ghosts” form of years past. However, Seattle’s current momentum feels like a freight train.
3. Houston Texans at New England Patriots
Upset Potential: Moderate
The Line: Patriots -3
This is the “Old Guard vs. New Wave” matchup. The Patriots have won eight straight Divisional Round games—an NFL record—while the Texans are looking for the first Divisional win in franchise history. New England has relied on a stifling defense and disciplined play, whereas Houston brings the explosive, “nothing-to-lose” energy of C.J. Stroud.
Why the Texans could surprise:
Houston’s demolition of the Steelers in the Wild Card Round (30-6) showed they aren’t just happy to be here; they are dangerous. C.J. Stroud has shown a remarkable ability to read complex coverages, the kind Bill Belichick’s successors still employ. If the Texans can get an early lead and force the Patriots to play from behind, the pressure shifts entirely to Foxborough.
The Patriots’ Edge:
Playoff experience in January at Gillette Stadium is a quantifiable advantage. The Patriots have a way of “shrinking the game,” forcing young teams into the one critical mistake that turns a 17-17 tie into a 24-17 loss.
2. Buffalo Bills at Denver Broncos
Upset Potential: High
The Line: Broncos -1.5
On paper, the No. 6 seed Bills playing at the No. 1 seed Broncos should be a clear victory for Denver. However, the betting lines tell a different story. Denver opened as a 1.5-point favorite, and the money has fluctuated all week. This is a rematch of last year’s Wild Card game where Buffalo embarrassed Denver 31-7.
The Case for the Bills:
Josh Allen is currently the “Final Boss” of the AFC. Without Patrick Mahomes or Joe Burrow in the bracket, Allen is the most experienced and dangerous playmaker left.5 He owns the best postseason TD-INT ratio in this millennium and is coming off a gutsy game-winning drive in Jacksonville. Buffalo’s offensive line is elite, which is the only way to survive a Denver pass rush that led the NFL with 68 sacks this year.
The Broncos’ Survival Guide:
Sean Payton is 4-0 in the playoffs coming off a bye. The Broncos’ path to victory involves rookie sensation RJ Harvey exploiting a Bills run defense that has been “leaky” all season.6 If Bo Nix can manage the game and avoid the turnovers that Josh Allen occasionally offers up, Denver should advance. But in a game this close, the “upset” of the No. 6 seed winning almost feels like the expected outcome.
1. Los Angeles Rams at Chicago Bears
Upset Potential: Maximum
The Line: Rams -3.5
This is the most fascinating game of the weekend. It features a No. 5 seed (Rams) favored on the road against a No. 2 seed (Bears). The narratives here are layered: the veteran Matthew Stafford returning to a cold-weather environment versus the “Chosen One” Caleb Williams in his first home playoff start.
The “Frozen” Factor:
The forecast for Sunday at Soldier Field is calling for “feels-like” temperatures well below zero and 20 mph wind gusts. Matthew Stafford has historically struggled in sub-freezing outdoor games (1-9 in rain/snow/extreme cold). While he’s planned to wear a “scuba suit” for warmth, the physical toll of a frozen football and a biting wind favors the team built for the elements.
Why Chicago is the Ultimate Upset Pick:
The Bears have lived on the edge all season, characterized by furious fourth-quarter rallies.7 They trailed Green Bay by 18 points in the Wild Card round before Caleb Williams orchestrated a stunning comeback.8 The Rams’ pass defense was the worst of any winning team last week (DVOA of 3.1%), and if they can’t put the Bears away early, the Soldier Field crowd will become a factor that Stafford and McVay might not be able to overcome.9+2
Divisional Round Summary Table
| Matchup | Favorite | Spread | Upset Likelihood |
| 49ers @ Seahawks | Seahawks | -7 | 15% |
| Texans @ Patriots | Patriots | -3 | 35% |
| Bills @ Broncos | Broncos | -1.5 | 50% |
| Rams @ Bears | Rams | -3.5 | 55% |
The Verdict
If you are looking for a “bracket buster,” look no further than Chicago. Despite being the higher seed, they are the underdog in the eyes of Vegas. The combination of a rookie quarterback playing with “house money,” a ferocious home-field weather advantage, and a Rams team that struggled to put away Carolina last week creates the perfect storm for a Chicago victory.
In the AFC, the Bills are the most dangerous lower seed in years. Josh Allen is playing with the desperation of a man who knows his Super Bowl window is wide open with Mahomes out of the way. Denver has the defense to stop most teams, but Josh Allen isn’t “most teams.”
By Monday morning, the NFL “final four” could look vastly different than anyone predicted in August. The next wave of superstars has arrived, and the Divisional Round is their coronation.
