**Buffalo Bills vs Kansas City Chiefs Prediction and Tips - NFL Week 9, 2025**

_By Ben Dunlop · Published: 3 Nov 2025, 08:25 am_

Buffalo Bills 28–21 Kansas City Chiefs in NFL Week 9 at New Era Field. Here's how the result stacked up against the model's call, with the win-probability story and where the value landed.

Buffalo led 21-13 at the break at New Era Field, and the second half did nothing to unsettle that. If anything, it hardened. Josh Allen found the end zone again with 1:38 left in the third to push it to 27-13, and by the time the quarter finished it was 28-13. Kansas City's only response came from Kareem Hunt with 11:34 left in the fourth, and the gap by then was too wide to close. Final score: Buffalo Bills 28, Kansas City Chiefs 21.

The scoring pattern tells its own story. Dalton Kincaid opened it for Buffalo in the first quarter, Rashee Rice hit back for Kansas City early in the second, then Ty Johnson and Allen either side of half-time turned a one-score game into a three-score one. Kansas City spent the whole night chasing points rather than dictating terms, and their only touchdown after the break arrived too late to matter.

The stat sheet backs up what the scoreboard suggests. Buffalo out-gained Kansas City 414 yards to 329, ran for 141 against 79, and posted an offensive EPA of 14.6 against Kansas City's 2.1. That's not a close contest by the numbers that actually decide these things. Buffalo didn't turn the ball over once. Kansas City did, and paired with a offense that couldn't get untracked, that was enough on its own.

Individually, Allen was close to faultless: 23 of 26 for 273 yards and a passing touchdown, plus two more on the ground. Patrick Mahomes, by contrast, needed 34 attempts to get to 250 yards, completed only 15 of them, and threw an interception. James Cook ran for 114 yards on 27 carries, and Kincaid was the busiest target on the field with 6 catches for 101 yards and a score. When your running back and tight end are both putting up numbers like that, the pass rush and the secondary don't need to be perfect, and Buffalo's weren't.

What makes this one interesting is how far it sits from the pre-match picture. Kansas City came in with the better quarterback rating, 89 to 62, and a stronger receiving corps, 70 to 56. Their form line read WLWWW against Buffalo's WWLLW, and the model had Kansas City winning 61% of the time with Buffalo favoured only narrowly on margin, by 3.3 points. The final gap was 7, more than double that projection, and the win itself ran contrary to the head-to-head split.

So the margin model was in the right neighbourhood. The favourite tag was not. Buffalo's backfield edge, 65 to 55 in the pre-match ratings, showed up exactly where you'd expect, in the rushing numbers and in Cook's night. Kansas City's talent advantage at the skill positions never turned into the yardage or the efficiency to back it up. Wins and misses, all of it, and this week the model's percentage call was the miss.
