The Bills ended the Chiefs’ undefeated season, but now they have to beat them in the playoffs

On the Chiefs’ next drive, Patrick Mahomes was intercepted with just over a minute left, and Buffalo kneeled out the clock. The Bills’ offense was the story of the game.

Kansas City entered Sunday’s game fifth in defense, allowing just 17.9 points per game. The Chiefs also had not allowed a team to score 30 points since the Philadelphia Eagles did so in Super Bowl 57 in February 2023.

Buffalo put an end to that thanks to a balanced attack. Allen threw for 262 yards, while the team ran for 104. (Allen was also the Bills’ leading rusher, with 55 yards.) Stability in both the passing and run games allowed Buffalo to control the ball for 34 minutes and three seconds. – Keep Mahomes off the field.

The Bills converted nine of 15 third downs, compared to just five of 10 for Kansas City.

Mahomes also struggled with his standards. He was intercepted on his first pass and was ultimately ineffective in the second half. Over the final two quarters, the Chiefs scored on just one drive, punting on their first two possessions before abandoning the desperation drive trailing by nine.

The loss is Kansas City’s first since Christmas, a span of 328 days.

While Buffalo is closer to securing first place in the AFC, that won’t be a silver bullet for the team in the playoffs.

Buffalo has defeated Kansas City four times in a row in the regular season, including three in a row. However, Mahomes and the Chiefs have never lost to the Bills in the postseason. Kansas City has defeated Buffalo in three straight playoff games, including at the Bills’ home stadium in January.

The loss dropped Kansas City to 9-1 and Buffalo improved to 9-2, leaving the Bills half a game out of first place in the conference.

Buffalo has a bye next week.

The Chiefs next play the Carolina Panthers.
