The Chiefs have experienced remarkable success throughout Patrick Mahomes' time with the team, securing three Lombardi Trophies and establishing themselves as the league's leading dynasty following the departure of Tom Brady from the NFL.
However, even the most dominant dynasties eventually crumble. No team, not even the Kansas City Chiefs, can maintain perfection indefinitely. Following a disappointing start where they lost six of their initial 11 games this season, the Chiefs now face the possibility of achieving their poorest performance since Patrick Mahomes joined the roster.
Mahomes and the Kansas City squad are still competing for a spot in the 2025 postseason. However, reaching the playoffs isn't a certainty. With an increasing number of defeats, some are questioning how this season would compare to the Chiefs' most disappointing recent years.
With that, here's what you need to know about Kansas City's worst records under Mahomes.

Patrick Mahomes' least successful season was in __PLH_2021, when he threw for __PLH_3,383 yards and __PLH_20 touchdowns, both career lows.
Since Mahomes became a member of the Chiefs in 2017, the team has experienced considerable achievement, reaching the postseason for seven straight years following his ascension to the starting role. Throughout this period, they've recorded three seasons with 12 victories, two seasons with 14 wins, and a 15-win performance in 2024.
The Chiefs' poorest showing with Mahomes at the helm was an 11-6 record in 2023. Andy Reid's squad lost five out of seven contests between Weeks 8 and 16. A surprising loss to the Raiders on Christmas Day was not fitting for a team aspiring to win the Super Bowl.
The Chiefs ultimately found their rhythm. They defeated the Dolphins, Ravens, and Bills with assurance, subsequently outscoring the 49ers in overtime to secure the Lombardi Trophy.
At this point, 11-6 is the best the Chiefs can hope for in 2025.
