Why the Chiefs Went 6–11 in 2025 and Spent This Week Rebuilding the Comeback

The Kansas City Chiefs walked into the 2026 offseason with the most jarring headline of the Patrick Mahomes era: a 6–11 record, a third-place finish in the AFC West and a nine-year division title streak snapped. If the final week of roster-building is any indication, the franchise treated that stumble as the blueprint for a serious reset.

On Aug. 31 the Chiefs revealed their initial 53-man roster, and the decisions that followed — plus the ones that came before — painted a clear picture of a team trying to fortify every weak point that sank Mahomes' worst full season as a pro.

Mahomes' 2025 numbers told the story

The quarterback's struggles were the engine of the collapse. Across 17 games Mahomes completed 62.8 percent of his passes for 3,587 yards, 22 touchdowns and 11 interceptions — but he was sacked a league-rocking 47 times, finishing with an 89.6 passer rating. The offense managed just 21.3 points per game while the defense surrendered 19.3, and Kansas City limped through its final five games empty-handed.

The message in the roster moves

Significant attention went into protecting and supporting the franchise signal-caller. The backup job is now Justin Fields' after Kansas City's overhaul at the position, while rookie third-stringer Garrett Nussmeier claimed jersey No. 19 — previously worn by Chris Oladokun, who landed on injured reserve. The bigger shakeup came in the backfield, where the Chiefs added Kenneth Walker to a crowded room. Walker arrives off a 2025 season with Seattle in which he carried 221 times for 1,027 yards and five touchdowns.

That crowded room produced one of the week's notable casualties: the Chiefs left running back Emari Demercado available on waivers, a calculated decision that signals real confidence in the rushers ahead of him.

Adding insurance elsewhere, Kansas City claimed defensive tackle Bryson Eason off waivers from the 49ers — a depth purchase on a defensive line anchored by Chris Jones but in need of reinforcements. The waiver wire giveth and taketh, though: one day after claiming a Buccaneers defender, the Chiefs saw cornerback Kevin Knowles poached by Tampa Bay, a reminder that cutdown-week margins are razor thin.

The unanswered question at receiver

Not everything Washington is settled. Just a week before opening night, the team's wide receiver room — featuring Rashee Rice, Xavier Worthy, Tyquan Thornton and undrafted-turned-rostered Andrew Armstrong — drew scrutiny for raising more questions than answers. Rice and Worthy combined for 1,103 receiving yards and just six touchdowns in 2025, and the Chiefs did little at the position during the offseason. With Travis Kelce still the TE1, the Chiefs are betting hard on internal development.

A market still believes

The odds board suggests bettors haven't abandoned the dynasty. Kansas City sits fifth in 2026 Super Bowl futures at +1500 on BetRivers, trailing only the Rams (+450), Bills (+1000), Ravens (+1000) and Seahawks (+1100). That's a reasonable snapshot of a roster that just got meaningfully deeper — even if it is not yet meaningfully proven at receiver.

The real test begins Sept. 15, when Kansas City hosts Denver in its home opener. The result of that game won't answer everything. But after a winless preseason, a lost 2025 and one of the busiest roster weeks in recent memory, it will show whether all this churn added up to a genuine bounce-back — or just more of the same.
