The Kansas City Chiefs entered their preseason matchup against the Arizona Cardinals under intense scrutiny, given their status as reigning Super Bowl champions and hopefuls for a historic three-peat. Despite a 20-17 setback in the opening preseason game, the Chiefs saw several roster hopefuls seize the moment and improve their stock. This article highlights three standout players who left a strong impression, enhancing their chances of securing a coveted spot on one of the NFL's most competitive rosters.

Jason Brownlee: Wide Receiver Poised to Overtake

One of the most talked-about upgrades following the game against the Cardinals was the performance of wide receiver Jason Brownlee. Brownlee made an immediate impact, catching a touchdown pass from Patrick Mahomes, showcasing his contested-catch ability and size advantage that many analysts felt elevated him above some established names on the roster.

His touchdown grab was more than just a scoring play; it was a statement. Brownlee demonstrated the length, size (6 feet 2 inches, 202 pounds), and athleticism that have been somewhat lacking among other receivers on the Chiefs' depth chart. Many observers are now pushing the notion that Brownlee deserves a chance to prove himself over Skyy Moore, whose preseason and prior performances have been underwhelming. Unlike Moore, Brownlee's display of raw receiving skill hinted at a receiver who could potentially develop into a reliable target for Mahomes, especially given his ability to make contested catches, an increasingly critical skill in the fast-paced AFC West.

The Chiefs' need for a dynamic receiving corps has been apparent, and Brownlee's rise in this game adds valuable depth to a group that includes proven veterans and recent draft additions. His stock is certainly on the rise as the preseason progresses, and his strong showing against a stout Cardinals defense only amplifies his chances to make the 53-man roster.

Jack Cochrane: Defensive Playmaker Forces Momentum

On the defensive side, linebacker Jack Cochrane stood out as a player who capitalized on his limited opportunities to make an explosive impact. Cochrane forced a fumble on the very first defensive play of the game, setting a tone for the Chiefs’ defense and underlining his ability to create game-changing plays.

Cochrane's quick presence and aggressiveness have made him a focal point of discussion among Chiefs fans and analysts alike. In a group that prides itself on speed and versatility, Cochrane’s knack for timely, high-impact plays could push him up the depth chart. His special teams contributions coupled with a high motor during defensive snaps make him a versatile asset in a fiercely contested roster battle.

Given the Chiefs' mix of veteran linebackers and promising youngsters, Cochrane's ability to deliver a big play early on shows the coaching staff that he can be trusted in high-leverage situations. The timing of this standout moment in a high-profile preseason game only raises his profile further, making him a serious roster candidate as Kansas City looks to maintain a championship-caliber defense.

Janarius Robinson: High-Motor Pass Rusher Making His Presence Felt

One more Kansas City Chiefs player whose stock improved in the preseason loss to the Cardinals is defensive end Janarius Robinson. Robinson stood out by making the only sack on the night for the Chiefs, showing impressive hustle and chase-down ability. His energetic and relentless pursuit of the quarterback highlighted his potential as a disruptive presence on the defensive line.

Robinson’s performance was a key highlight on a defense looking to maintain its championship-caliber level, and his ability to get to the passer in a high-profile preseason game makes a strong case for him to earn more opportunities and potentially secure a roster spot. This kind of impactful play early in the preseason can only boost his standing with the coaches as the Chiefs finalize their roster.

Despite the narrow loss to the Cardinals, these three players—Jason Brownlee, Jack Cochran, and Justyn Ross—were clear winners in the eyes of coaches and fans. Each showed elements of growth, readiness, and playmaking that could earn them roles on the Chiefs' 2025 roster.

The Chiefs have a storied tradition of finding diamonds in the rough during training camp and preseason. These hopefuls exemplify that spirit as they push for chances to contribute to a team aiming to make history with a third consecutive Super Bowl championship. Their performances provide a glimpse into the depth and talent Kansas City possesses beyond its established stars, and their stock will likely continue to rise as the preseason progresses.
