The Kansas City Chiefs, with Patrick Mahomes at their helm, spent a decade as the NFL’s unbeatable heavyweight. However, Colin Cowherd says Sunday night’s 20–10 loss against the Houston Texans was the clearest sign yet that the dynasty is cracking right in front of our eyes.On Sunday, at 'The Herd,' Cowherd compared the Chiefs’ slide to the sad final chapter of Muhammad Ali’s career — not a dramatic knockout, but a slow, painful unraveling. And for Mahomes’ Chiefs, Cowherd believes that unraveling is underway.“They look a little slower… Travis Kelce..... with another big drop, no pass rush, the O-line got pushed around, they don’t have a running game,” Cowherd said. “This is how dynasties end. They don’t fall off a cliff......""They dominate for years, go to Super Bowls iwin Super Bowls, and then they start winning really close games. That was Kansas City last year, and then they start losing all those close games. Oh, wait, that's Kansas City this year."Cowherd pointed out the Chiefs are 0–4 this season when Mahomes is their leading rusher. He symbolizes this stat with how broken the roster has become.“Trust your eyes… Kansas..... City needs a reboot. Maybe even a rebuild.”For the first time in Mahomes’ era, the Chiefs look human, and the NFL is smelling blood.Also read: "This is basically bullying": Taylor Swift fans haunted by ghosts of Jason Kelce's decision after Travis' latest gesture in Chiefs' SNF lossAlso read: Patrick Mahomes doesn't hold back on Travis Kelce's costly game-ending error as Chiefs' playoff hopes get crushed vs. Texans on SNFPatrick Mahomes and Chiefs face doomsday playoff odds with brutal 2026 scheduleThe Patrick Mahomes-led team is on the ropes, and the numbers are uglier than anyone in Chiefs Kingdom could’ve imagined. After Sunday’s home loss to the Texans, the defending AFC champs dropped to 6–7.It’s their most losses in a season since Mahomes became the starter in 2018. They've not been under .500 since 2012, and they’ve already been eliminated from winning the AFC West, ending a nine-year reign of dominance. But the bad news doesn’t stop in 2025.The Chiefs’ 2026 opponent slate is a tough one, with road trips to Buffalo, Seattle and the Rams possibly including Cincinnati, plus home dates with the Patriots, Jets, Dolphins, and 49ers.Worse yet, Kansas City enters the offseason $42.7 million over the cap, limiting its ability to fix issues on the offensive line, pass rush and receiver room.
