Few rivalries in the NFL carry the electricity, emotion, and sheer star power of Chiefs vs. Bills. When Patrick Mahomes and Josh Allen take the field, fans know to expect fireworks. This Week 9 clash in Orchard Park should be no different.
The Kansas City Chiefs (5-3) have shaken off their slow start and reclaimed their identity as one of the league’s elite. They’ve won five of their last six and rediscovered their balance on offense. Mahomes is back to his MVP-level brilliance. He is spreading the ball efficiently while the defense continues to generate turnovers and key stops.
Meanwhile, the Buffalo Bills (5-2) are on less solid ground. Coming off a commanding Week 8 victory over the Carolina Panthers, Buffalo bounced back from back-to-back losses to the Patriots and Falcons. Despite that, Allen looks dialed in. He leads an offense that can score from anywhere on the field. At home in front of the Highmark Stadium crowd, the Bills are eager to avenge their AFC Championship loss to Kansas City last season. This game doesn’t just shape playoff seeding. It could be a preview of the AFC title game once again.

Here we will look at and discuss some bold predictions for the game between the Bills and the Chiefs in Week 9 of the 2025 NFL season.
This is bold but rooted in history. As dominant as Mahomes has been overall, Allen has consistently had his number in regular-season meetings. The Bills quarterback owns a 4-1 record against Mahomes in the regular season. Allen has often outperformed Mahomes statistically, even if postseason history tells a different story.
Allen has been on a tear in 2025. He is efficiently blending power and precision as both a passer and runner. At home, where he feeds off the energy of Bills Mafia, expect him to put up gaudy numbers again. He will have something in the neighborhood of 300+ total yards and three touchdowns. Mahomes will play well, as he always does. Allen’s mobility and deep-ball aggression, though, could make the difference in moving the chains and sustaining drives.
That said, while Allen may win the statistical battle, Mahomes could still win the war. The Chiefs’ offense is humming again after a rocky September. Mahomes remains the most dangerous player in football when it matters most. Expect him to keep pace with two or three scores of his own. Still, Allen will narrowly edge him in total production by game’s end.
If the Chiefs want to control tempo and keep Allen on the sideline, Isiah Pacheco will be their most important weapon. The bruising running back has not been a steady force all season. He hasn’t yet hit the 100-yard mark in a single game. If Pacheco plays in Week 9, that will change.
The Bills’ defensive front has shown cracks...
