For most of the Patrick Mahomes era, predicting the Kansas City Chiefs required very little courage. You picked them to win the AFC West, assumed they would still be playing in late January and trusted Mahomes to repair whatever looked broken by the time the games mattered. The Chiefs turned concern into a recurring television segment rather than a genuine condition.

That habit should end now.

Kansas City went 6-11 last season. Mahomes tore the ACL and LCL in his left knee in December. Travis Kelce is returning for a 14th season, but the version of Kelce who could erase a bad offensive plan through instinct and chemistry is now part of the team’s history, not a reasonable weekly expectation. The secondary has been rebuilt again, this time after moving Trent McDuffie and losing Jaylen Watson.

The Chiefs will improve in 2026. They will probably return to the playoffs. They will not return to the AFC Championship Game. The window is not closed, because a window with Mahomes is never completely closed. It is narrower than the franchise and much of the league are willing to acknowledge.

Mahomes’ return is not the same as Mahomes being whole

The most encouraging news from Kansas City is that Mahomes has progressed well enough to participate in offseason work and continues to target Week 1. That is a remarkable recovery trajectory. It is not proof that the quarterback who begins the season will move, reset and improvise like the one the league has spent years failing to contain.

Mahomes’ mobility has never been about raw rushing totals. It is the half-step that turns a clean defensive win into a six-second scramble drill. It is the retreat that invites a pass rusher to chase before Mahomes changes his arm angle and finds a receiver behind him. A repaired knee does not need to make him immobile to change the offense. It only needs to take away a small amount of trust in the movement that has always saved Kansas City from imperfect protection and imperfect spacing.

Justin Fields is a logical insurance policy and a fascinating change-up. He is not a substitute for Mahomes. If Fields has to play meaningful September games, Kansas City will be managing the standings before its best player is fully ready, not simply waiting for the offense to warm up.

The old answers are aging out

Kelce’s return matters because his connection with Mahomes remains the most stable feature in the offense. It also highlights the problem. Kansas City is still asking a tight end approaching the end of his career to provide the clarity that the wide receiver room and protection have not consistently supplied.

Eric Bieniemy’s return as offensive coordinator should help. During his first run in that role, the Chiefs never finished lower than sixth in points or yards. In the three seasons after he left, their average rankings fell into the middle of the league. Bieniemy brings standards, detail and a familiarity with Mahomes that few coaches can match.

He does not bring back Tyreek Hill’s speed, Kelce’s younger legs or the offensive line that allowed Kansas City to play with patience. Coaching can restore sharpness. It cannot reverse age or turn every replacement into the player who left.

The Kenneth Walker III signing is Kansas City’s clearest admission that the offense needs a different source of stability. Walker can create explosive runs without perfect blocking and should reduce the number of games in which Mahomes has to manufacture the entire scoring output. That is smart roster building. It is also a sign that the old formula – Mahomes plus situational brilliance – is no longer enough.

The defense has earned trust, not immunity

Steve Spagnuolo has rebuilt defensive rooms so often that turnover barely registers as a concern anymore. Kansas City traded McDuffie, allowed Watson to leave and still expects to field another disciplined secondary around young corners and returning veteran L’Jarius Sneed. The Chiefs used the sixth overall pick on Mansoor Delane, a clear investment in keeping the coverage unit fast and inexpensive.

Spagnuolo deserves the benefit of the doubt. But there is a difference between developing one new corner inside a stable secondary and asking several new pieces to replace proven players while the offense searches for itself. Young defensive backs make mistakes. A healthy Mahomes used to make those mistakes survivable. A recovering Mahomes leading a mid-tier offense may not.

The AFC West is less forgiving now as well. Denver enters the season with continuity and a quarterback who nearly reached the Super Bowl in his second year. The Chargers remain capable of winning ugly games. Even if Kansas City rebounds, the automatic divisional cushion is gone.

The case against me

The counterargument begins and ends with the two people who have made pessimism look foolish for most of the last decade: Mahomes and Andy Reid. Add Bieniemy, Walker and a Spagnuolo defense, and it is easy to imagine Kansas City becoming the team no contender wants to see in January. The Chiefs have reinvented themselves before. They won after trading Hill. They won with a defense-first identity. They have spent years succeeding after the public declared the offense solved.

That history matters. It does not guarantee that every decline is temporary. Great organizations do not collapse on schedule; they erode at the edges until the quarterback is asked to cover too many of them at once. Last season was the first time the erosion reached the record. The knee injury makes it harder to assume an immediate correction.

Where I land

Kansas City will be better than 6-11. Bieniemy will give the offense more structure, Walker will give it a more credible ground game and Mahomes will produce enough high-level football to put the Chiefs back in the postseason.

But the old standard matters. A wild-card berth is not evidence that the championship machine has been repaired. It is evidence that Mahomes remains extraordinary. The Chiefs will finish second in the AFC West and be eliminated before the AFC Championship Game. That would be a successful recovery season for most franchises. For Kansas City, it will confirm the uncomfortable truth: the dynasty’s window is still open, but it is no longer wide enough to climb through casually.

What to watch

The first signal is Mahomes’ willingness to escape left and throw after resetting his feet. The second is whether Walker creates efficient offense without forcing Kansas City into predictable personnel. The third is Delane’s early role in the secondary. If all three stabilize quickly, the Chiefs can challenge this projection. If even one lags, Kansas City will spend 2026 proving it is mortal.
