The Kansas City Chiefs are currently staring into a mirror and barely recognizing the reflection staring back. For nearly a decade, the pairing of Patrick Mahomes and Andy Reid was the gold standard of offensive innovation, a relentless juggernaut that treated NFL secondaries like a personal playground. But the 2025 season delivered a reality check that felt more like a tectonic shift: for the first time in his career, Patrick Mahomes missed the playoffs.
This isn’t just a “down year” or a statistical anomaly. This is a fundamental collapse of a system that once felt invincible. Mahomes just posted career lows in completion percentage, touchdown rate, and sack-per-pressure metrics. An offense that was once a perennial top-five unit in scoring has plummeted to 20th in the league. How does the greatest quarterback of his generation, paired with a Hall of Fame coach, suddenly produce a legitimately bad NFL offense? The answer isn’t a single missed throw or a bad call; it is a complex, multi-branched “problem tree” rooted in the fact that while the NFL evolved, the Chiefs stayed exactly where they were in 2018.
The 2018 Time Capsule: A Dynasty Built on Air
To understand the current crisis, we have to look back at the origins of the Mahomes era. In 2018, the Chiefs were the ultimate disruptors. They ran a spread-formation heavy offense designed to stretch defenses to their absolute breaking point. They were top five in passing rate every year because they could afford to be. With Tyreek Hill’s vertical gravity and Travis Kelce’s ability to find the “void” in any zone, business was booming.
Andy Reid was an early adopter of the RPO (Run-Pass Option), a collegiate concept that forced NFL defenders to make impossible choices in real-time. If they crashed to stop the run, Mahomes threw behind them. If they stayed home, he handed it off. It was a masterpiece of modern design that fueled a dynasty. However, the NFL is an ecosystem that demands constant evolution. As the years ticked by, the innovation that made Kansas City unique became the very thing that made them predictable.
The Umbrella: How Defenses Caged the GOAT
The shift began in 2021. Defenses across the league realized that the “one-high safety” look—the standard for decades—was suicide against Mahomes. Teams began dropping a second safety deep, creating what analysts call a “shell” or “umbrella” coverage. This forced the Chiefs to abandon their deep-shot identity. Mahomes’ average depth of target (ADOT) began a steady, painful decline, falling from 9.1 yards in his rookie year to a staggering 6.2 in 2024.
By 2025, the “shell” had effectively neutralized the explosive plays that defined the Chiefs. But this presented a massive opportunity that the Chiefs simply refused to take. When you put two safeties deep, you take one body out of the “box” near the line of scrimmage. Mathematically, the offense has a massive advantage in the running game. If the defense dares you to run, a modern offense should feast.
Unfortunately, Andy Reid’s Achilles’ heel has always been his undying love for the pass. Even when the math screamed “run the ball,” the Chiefs stayed in the shotgun.
The Shotgun Trap: Why the Running Game is Broken
One of the most damning aspects of the current Chiefs offense is their reliance on the shotgun formation. In 2025, they utilized the shotgun 80% of the time—the third-highest rate in the league. While this is great for a passing-centric team, it is catastrophic for a modern running game.
When a running back like Kareem Hunt starts from a shotgun alignment, his body positioning is fundamentally limited. Film analysis shows Hunt often starting with his chest facing the sideline. This limits his vision to the front side of the play, effectively deleting “cutback lanes” on the back side of the offensive line. In a world where defenses are flying to the ball, the ability to cut back into an open gap is the difference between a two-yard gain and a twenty-yard explosive play.
Running from under center allows the back to face the line of scrimmage with his full chest, granting him 180-degree vision of every gap. By staying in the shotgun, the Chiefs have turned their running game into a predictable, one-dimensional afterthought. For years, this didn’t matter because the passing game was so elite it covered the cracks. In 2026, those cracks have become canyons.
The Talent Leak: From Elite Weapons to “Kardashian” Rotations
Schemes are only as good as the players executing them. The loss of Tyreek Hill was the first major blow, but the slow, natural decline of Travis Kelce has been the final straw. The entire concept of the “spread” is to force defenders to cover your talent in space. But when the talent declines, you aren’t stressing the defense—you’re exposing your own players.
The Chiefs’ 2025 season looked like a desperate experiment in finding an “X” receiver—the isolated threat who can win one-on-one matchups on the outside. They cycled through Xavier Worthy, Rashee Rice, Hollywood Brown, and Tyquan Thornton with the frequency of a tabloid gossip column. The result? Total disrespect from opposing defenses.
In the past, you wouldn’t dream of leaving a cornerback alone with Tyreek Hill. You needed safety help. Now, defenses are sticking their corners on the Chiefs’ wideouts in man-to-man coverage and using that extra safety to bracket the middle of the field or “cut” the crossing routes that Mahomes loves. When nobody on the outside can create vertical separation or win a jump ball, the entire offensive geometry collapses.
The Ultimate Disrespect: The Denver Blueprint
Nothing illustrates the Chiefs’ downfall better than the film from their matchups against the Denver Broncos. The Broncos showed the ultimate sign of schematic disrespect. Knowing the Chiefs couldn’t hit a deep post to save their lives, Denver would keep a single high safety but tell him to ignore his deep responsibilities.
Instead of staying deep to prevent the home-run ball, the safety would “cut” under the crossing route, meeting the receiver right as Mahomes let the ball go. It’s a gamble that assumes the quarterback won’t or can’t make the defense pay deep. In 2025, that gamble paid off every single time. Mahomes, once the master of the “extend-the-play” magic, seems to have lost his “mind-meld” connection with a struggling Kelce. Without that voodoo magic and without a deep threat, the Chiefs are just an average team playing in a predictable system.
The Kenneth Walker Factor: A New Hope?
So, how do the Chiefs fix a problem this deep? They’ve already taken the first step by acquiring Kenneth Walker. This is the first time since Kareem Hunt’s first tenure in 2018 that the Chiefs have had a truly dynamic, game-changing piece in the backfield.
But Walker alone isn’t the cure. The Chiefs have to innovate toward the modern NFL “meta.” This means going under center. It means building an identity around the ground game to force those safeties to creep back down into the box. If Walker can become a legitimate threat that demands an eight-man box, the “shell” coverage will finally break.
The meager group of receivers currently on the roster doesn’t need to be elite; they just need to face less crowded coverages. If the run game is working, the man-to-man matchups become easier, and the play-action passing game—something the Chiefs have ignored for far too long—can finally return to prominence.
The Verdict: Can the Dynasty be Rebuilt?
Patrick Mahomes is still Patrick Mahomes. His physical tools are intact, his ACL is strong, and his competitive fire hasn’t dimmed. But the “Superman” era of his career, where he could overcome bad play-calling and mediocre talent with sheer will, is over. The NFL has solved the 2018 version of the Kansas City Chiefs.
To win the “whole damn thing” in 2026, Andy Reid must do the one thing he has resisted for decades: he must embrace the balance. The path back to the Super Bowl isn’t through the air—it’s through the dirt. It’s about under-center formations, cutback lanes for Kenneth Walker, and punishing defenses for their disrespect.
The Chiefs are no longer the hunters; they are the hunted. The league has caught up, and now the greatest coach-quarterback duo of all time must prove they can do more than just innovate—they must prove they can adapt. If they don’t, the 2025 season won’t be remembered as a fluke; it will be remembered as the end of an era.
