Match Overview

Core Team Statistics: Bills vs Chiefs

Third-Down Efficiency

• Buffalo converted 60% of its third downs, over 9 of 15 attempts, extending drives and pinning the Chiefs' defense on the field for more than 34 minutes.
• Kansas City's 5-of-10 mark hides the real problem — the Chiefs managed just 25:57 of possession, meaning their defense was under siege for most of the night.

Rushing Balance & Ball Control

• The Bills committed to the ground game, racking up 31 carries for 104 yards and three rushing touchdowns against a Chiefs front that surrendered only 78 rushing yards on 17 carries.
• Buffalo's 0 sacks allowed versus Kansas City's 2 tells the story of the line of scrimmage: Josh Allen had a clean pocket all night while Mahomes was flushed from his.

Takeaway Battle

• Buffalo won the turnover battle 2-1, intercepting Mahomes twice, and turned that field position into points.
• The Chiefs gave up 107 more total yards and 8 more minutes of possession, and that discrepancy decided the game more than any single play.

Buffalo Bills Player Statistics

Josh Allen — QB

Josh Allen was the engine of the whole night. He distributed to eight different receivers, avoided a single sack, and added the longest, loudest play of the game — the 26-yard fourth-down sprint that put Buffalo up double digits late.

James Cook — RB

Cook took just nine handoffs but turned them into two goal-line touchdowns, giving the Bills an early lead and a physical identity near the end zone.

Khalil Shakir — WR

Shakir was the short-area chain mover, collecting a team-best 70 yards and repeatedly moving the sticks on third down.

Curtis Samuel — WR

Samuel's fourth-quarter touchdown catch extended the Buffalo lead and forced the Chiefs into a one-score, must-scoring chase.

Kansas City Chiefs Player Statistics

Patrick Mahomes — QB

Mahomes put up three touchdown passes but was under heavy duress all night, absorbing blitz pressure on nearly half his dropbacks and throwing two picks that turned the game.

Kareem Hunt — RB

Hunt was the Chiefs' only consistent ground threat, but Kansas City managed a meager 78 rushing yards on 17 carries and rarely controlled the clock.

Xavier Worthy — WR

The rookie added a 15.0 average depth of target and a long touchdown, yet the passing game still netted just 196 yards against the Buffalo secondary.

Noah Gray — TE

Gray was a red-zone target twice and finished both times, but 23 receiving yards shows how little clean yardage the Chiefs created after the catch.

Statistical Leaders: Bills vs Chiefs

Why Buffalo Won

Balanced Offensive Production

The Bills spread the ball across eight different receivers and attacked with both the pass and the run. Josh Allen threw for 262 yards while the backfield added 104 on the ground, and the result was a 107-yard, 8-minute edge in total yardage and possession.

Ground Game & Goal-Line Efficiency

Buffalo committed to the run on a 31-carry night and leaned on Cook and Allen near the goal line. Three rushing touchdowns plus a clean, zero-sack pocket kept the offense ahead of the sticks.

Forcing Mahomes Into Mistakes

The Buffalo defense pressured Patrick Mahomes on 48.6% of his dropbacks and intercepted him twice. Those takeaways flipped field position and kept the Chiefs' offense from ever building a long, sustained lead.

Why Kansas City Lost

Heavy Pressure on Mahomes With No Run Relief

Kansas City's offense leaned almost entirely on the pass. The Chiefs rushed for just 78 yards, and with a 48.6% pressure rate on Mahomes, turnovers became inevitable.

Third-Down Stalls and Lost Time of Possession

The Chiefs converted only 5-of-10 third downs and won the possession battle by a full eight minutes less than Buffalo. Shorter possessions meant fewer chances to climb back once they trailed.

Inability to Stop Fourth-Down Heroics

Kansas City couldn't do anything about Josh Allen's 26-yard touchdown scramble on fourth down with 2:17 left, a play that all but iced the game and erased any hope of a miracle finish.

Season Series & Historical Context

The Week 11 win was Buffalo's second straight home win over Kansas City, and it snapped the reigning champion Chiefs' 9-0 start. For Josh Allen, it marked another chapter in his long-running, entertaining quarterback rivalry with Patrick Mahomes. The two later met again in the AFC Championship on January 26, 2025, where the Chiefs edged the Bills 32-29 — a reminder of just how thin the margin between these two franchises has become.

Advanced Statistical Insights: Josh Allen's Efficiency

Josh Allen's 27-of-40 passing line looks modest next to his 262 yards, but the advanced numbers reveal a quarterback who was both safe and explosive. He produced 144 yards after the catch, meaning his receivers were gaining chunks on their own, and he completed passes to eight different targets. Allen added 55 rushing yards on 12 carries while absorbing zero sacks, giving him a clean 317 yards of total offense with just one turnover.

The assist-to-scoring breakdown is telling. Allen converted 13 first downs through the air while extending drives with his legs, and Buffalo's 9-of-15 third-down success kept possessions alive. That efficiency per possession — 366 yards on a long, sustained set of drives — is exactly why the Bills controlled the clock for 34 minutes. Mahomes, by contrast, threw 3 touchdowns but racked up 105 yards after the catch on just 196 total passing yards, a sign that Kansas City's production was built on short, high-variance plays that two interceptions wiped away.

Game Implications & Key Lessons

What This Means for Buffalo

• The Bills proved they can beat the NFL's best when the stakes are high, giving the locker room real belief heading into the stretch run.
• Josh Allen's dual-threat floor remains the team's ceiling; his 317 total yards and zero-sack night validated the offense's identity.
• Buffalo's defense showed it can pressure Mahomes and create takeaways, a blueprint they can carry into the postseason.

What This Means for Kansas City

• The loss exposed a run game that produced just 78 yards and an offensive line that let Mahomes take pressure on nearly half his dropbacks.
• Two interceptions from Mahomes were the difference, and the Chiefs need cleaner third-down execution against elite fronts.
• Kansas City must find a way to protect the football and control the clock, or these narrow margins become losses more often.

Key Lessons from the Game

• Control the clock and your own mistakes; Buffalo won the possession battle on its way to a 107-yard edge.
• A zero-sack night for the quarterback is worth more than a big yardage total.
• Takeaway differential is the quickest way to flip a game against a great opponent.
• Rushing touchdowns near the goal line keep you ahead of the sticks and the scoreboard.
• Deep, balanced receiving production beats one superstar target in a grind-it-out game.
• Defense that pressures the opposing QB negates even elite short-game efficiency.
