Chiefs Preseason Opener: Emerging Stars, Alarming Penalties, and the Battle for Depth

The Kansas City Chiefs kicked off their 2026 preseason campaign against the Los Angeles Rams, and while the final score might not have swung in Kansas City’s favor, the outing offered a treasure trove of information regarding the team’s roster depth. For the coaching staff and the fervent fanbase, preseason games serve as a vital laboratory—a place where the focus shifts from final results to the development of young talent, the evaluation of backup roles, and the identification of potential liabilities. As the team looks to refine its identity for the upcoming regular season, the performance against the Rams highlighted exactly where the Chiefs are thriving and, perhaps more importantly, where they face significant danger if injuries occur.

At the center of the positive takeaways was rookie running back Emmett Johnson. Entering the game with a point to prove, Johnson looked like the explosive answer to the backfield’s lingering questions from the previous season. Fans have grown accustomed to a certain style of running, but Johnson brought a distinct brand of vertical explosiveness that was largely absent in 2025. He was decisive, head-down, and willing to navigate the trenches with a level of burst that energized the offense. While it is crucial to temper expectations—given that the Rams, under Sean McVay, opted to sit their starters and even most primary rotational defenders—Johnson’s performance felt like a genuine statement. He finished with a solid workload that showcased his ability to hit the hole and punish the defense, proving that he has the traits necessary to potentially seize the RB2 role and provide the relief that star running back Kenneth Walker needs to remain effective throughout the grueling 17-game schedule.

Defensively, the spotlight shone brightly on Jaden Hicks. Often overshadowed in training camp by other rotation members, Hicks treated this game as his personal showcase. Playing against a mix of second and third-stringers, Hicks looked physically superior, dominating his assignments and effectively forcing the Rams’ offense to scheme around him. His ability to read the field was maturity personified. The standout moment came in the end zone, where he perfectly read a pass attempt from Ty Simpson to Max Claire and knocked it down, preventing a near-certain touchdown. With a team-high in tackles and a crucial tackle for loss, Hicks proved he is ready to contribute, and his performance suggests that the coaching staff has a legitimate weapon waiting in the wings of the secondary.

The quarterback competition also provided some of the most compelling drama of the afternoon. While Justin Fields currently holds the position of QB2 on the depth chart, his limited time on the field left much to be desired. He finished four-of-four for 41 yards, yet the box score masked a concerning trend: a hesitation to process the field and an apparent reliance on simple, safe reads. In contrast, Garrett Nussmeier delivered a performance that felt like a breakthrough. Nussmeier operated with a level of confidence and rhythm that stood out, particularly on a scramble drill where he kept his eyes downfield, processed his options, and fired a precise pass into a tight window. Nussmeier is beginning to flash the same traits that defined his 2024 campaign at LSU, presenting a scary prospect for the rest of the league: a backup quarterback with real developmental ceiling behind Patrick Mahomes. If Nussmeier continues to refine his decision-making, he not only secures his spot but also becomes a valuable asset for the franchise’s future.

However, the game was not without its “disasters.” The most glaring issue, and one that should keep the coaching staff up at night, was the performance of the offensive line’s depth. The statistics are nothing short of abysmal: 12 penalties for 83 yards. While one must account for the fact that these were primarily second and third-string linemen, such a lack of discipline is unsustainable. The list of infractions—ranging from repeated holding calls and false starts to illegal men downfield—undid drive after drive, effectively killing any rhythm the offense attempted to establish. At one point, a potential touchdown was erased by a holding penalty, and a crucial first-down conversion was negated by an illegal man downfield call.

This lack of cohesion and discipline serves as a stark warning. The NFL is a game of attrition; injuries are inevitable. Should a starter go down in the regular season, the team is forced to rely on these backups. If a substitute player commits three penalties in a two-drive span, they effectively sabotage the entire offensive unit and surrender scoring opportunities. The preseason is supposed to expose these weaknesses, and the offensive line failed to provide any confidence in the team’s depth. It creates an environment where the coaching staff must now prioritize remedial discipline training for these units before the regular season begins in earnest.

Beyond the trenches, the team’s red zone efficiency remains a significant concern. Finishing zero-for-three in the red zone is a statistic that will haunt any coaching staff. While the play-calling was understandably vanilla—as teams rarely reveal their true schemes during the preseason—the inability to execute inside the 20-yard line was frustrating. The nadir of the game occurred during a collaboration between Nussmeier and Johnson, where a backwards throw that resulted in a six-yard loss stalled a promising drive. It was a teachable moment regarding ball security and decision-making, but it encapsulated the overall struggle to capitalize on opportunities.

Despite these hurdles, the performance of veteran kicker Harrison Butker provided a much-needed steady hand. Scoring all 12 of the team’s points and converting a 59-yard field goal, Butker reminded everyone why he remains a pillar of reliability for Kansas City. Additionally, defensive standout Armesason Thomas provided a highlight-reel play, flying off the edge to break up a Hail Mary attempt just before the half, signaling that the defensive energy remains high even when the secondary units are on the field.

Ultimately, the first game of the 2026 preseason was exactly what it needed to be: a mirror. It reflected the brilliance of young players like Emmett Johnson and Jaden Hicks, and it brutally highlighted the lack of discipline and depth within the offensive line. As the team moves forward, the challenge will be bridging the gap between this talented core of starters and a backup unit that is clearly still learning the fundamentals of professional intensity. The coaching staff has the data they need; now, they have the time to turn these lessons into the discipline required to win championships. The path to a successful season is rarely paved with easy victories; it is forged in the grit and the corrections made during these long, hot, and often frustrating summer days on the practice field and in these preseason exhibition games.
