Patrick Mahomes has walked off the field with a loss just 36 times in his NFL career, playoffs included. And out of those 36 defeats, only five have been full-blown blowouts by more than two possessions. That’s just how rarely Mahomes and the Kansas City Chiefs get punched in the mouth.
At 5-1, Kansas City is still in a pretty good spot, with its only blemish coming on the road against the Seattle Seahawks. But Sunday night’s 20-3 beatdown was a wake-up call the Chiefs couldn’t afford to ignore.
Nobody expects a team to go 19-0, and even the best contenders are bound to take an L eventually. But this wasn’t just another loss on the schedule. The Chiefs got thoroughly outplayed, their offense had no answers, and their first defeat of the season left plenty of reasons for concern in Kansas City.
Seahawks Expose Chiefs’ Biggest Flaw In Ruthless Takedown
The Seahawks’ defense has a way of making even the best offenses look ordinary. But for the Kansas City Chiefs, Sunday night’s beatdown also reignited a familiar concern: Does Mahomes’ weapons have enough juice to get the job done? Nobody stepped up against Seattle, and Kansas City’s leading receiver managed just 44 yards. That’s hardly the kind of production you want from a Super Bowl contender.
The problems weren’t limited to the offensive side of the ball, either. Kansas City’s defense struggled to get off the field, allowing the Seahawks to move the chains on third down almost at will. Seattle repeatedly came through in clutch situations during its 20-3 win at Lumen Field, exposing a weakness that haunted the Chiefs throughout the 2025 season.

It started on Seattle’s second drive, when Sam Darnold and company faced third-and-9 twice and third-and-7 once. All three times, Kansas City gave up the first down, allowing the Seahawks to march downfield and settle for a field goal.
And that was just the beginning.

Chiefs’ Third-Down Defense Crumbles Against the Seahawks
On Seattle’s opening scoring drive, the Chiefs surrendered conversions on two separate 3rd-and-9 situations. Later, Darnold picked up seven yards on third-and-6, while Jaxon Smith-Njigba hauled in his touchdown on third-and-9. Darnold also moved the chains on third-and-9 and third-and-10 during another scoring drive, and Seattle found the end zone again on third down.
Seattle became the first team to put the clamps on Kenneth Walker III this season, and once the run game stalled, the entire Chiefs offense went off the rails. Mahomes’ squad finished with just three points, 213 total yards, and 11 first downs — all career lows for a Mahomes-led start.
Simply put, the Chiefs couldn’t get off the field when it mattered most.
Third-down defense was a glaring Achilles’ heel for Kansas City in 2025, and for the first time this season, those old problems came roaring back. Seattle finished 11-of-16 on third down, keeping drives alive, dictating the tempo, and putting the Chiefs’ defense on its heels all night.
If Kansas City wants to bounce back, solving their third-down problem has to be near the top of the to-do list.
Last Word on Chiefs
The Chiefs were never going to run the table all season, but Sunday night’s beatdown in Seattle exposed some cracks in the armor that Kansas City can’t afford to ignore.
The Chiefs rolled into Seattle at 5-0 and atop the NFL in total offense, looking every bit like a team ready to make another deep playoff run. But the issues they’d managed to paper over during their unbeaten start finally came back to bite them. One loss doesn’t erase a red-hot start, but it gives Andy Reid and his coaching staff plenty of film to dissect before the next kickoff.
And honestly, there weren’t many silver linings in Kansas City’s 20-3 loss. The offense couldn’t stay on schedule, the pass rush failed to generate pressure, and the offensive line had its hands full all night. Add Harrison Butker’s ongoing struggles to the mix, and the Chiefs suddenly have a lot more to clean up than just the scoreboard.
The sky isn’t falling in Kansas City, but Sunday’s dud was a reminder that even a 5-0 team has flaws — and the rest of the league just got a fresh look at them.
