The Kansas City Chiefs are 5-1, yet their dynasty is facing its toughest test since Patrick Mahomes arrived. A year after missing the playoffs, they are trying to prove the old standard still applies in a deeper AFC. Here is why the challenge looks bigger than ever.
The Fall That Started It
In 2025 the Chiefs went 6-11 and missed the playoffs for the first time since 2014, ending a run of 10 straight postseason appearances. Mahomes tore his left ACL in December, in the same loss to the Chargers that eliminated Kansas City. The Denver Broncos finished 14-3 and ended the Chiefs’ nine-year run as AFC West champions.
The 2026 Rebound
Mahomes started Week 1 against Denver, and the Chiefs won 31-10. Kansas City added running back Kenneth Walker III in the offseason and reached 5-0 before a 20-3 defeat at Seattle on Sunday Night Football. At 5-1 they lead the AFC West, and Mahomes has thrown for about 1,470 yards and nine touchdowns, according to ESPN, with a QBR near 66.
A Tougher Conference
The AFC no longer feels like a one-team league. Buffalo is also 5-1, while Denver, Cleveland and Pittsburgh sit at 5-2. The Chiefs visit Denver on November 1 (US time) and Buffalo on November 26. Both games could decide the top seed.
The Offense Question
Scoring only three points in Seattle was a reminder that the offense is still evolving. It also showed how thin the margin is for a team that, over the past decade, has reached five Super Bowls and won three of them. A preview before the season said even a wild-card or divisional exit would feel like a disappointment after last year.
So Is the Dynasty Over?
Not yet. A top AFC record and a healthy Mahomes keep the Chiefs in contention. But “biggest challenge yet” is fair, because the team must beat a stronger field without the cushion of past dominance. The next month, including the Broncos and Bills games, will show whether the dynasty is still intact. Standings change weekly, so check the latest results.
