Seahawks close preseason in Kansas City with attention on Trevon Diggs’ debut and the Jalen Milroe competition

The Seahawks’ preseason schedule concludes in Kansas City, and the team is treating Friday night as a last, public sorting process for players fighting for roles. In an official preview, Seattle framed the game as a showcase for anyone who needs to prove they can contribute, while also giving coaches one more controlled opportunity to iron out mechanics and execution before the regular season begins.

One of the primary storylines in the Seahawks’ own preview centers on Trevon Diggs’ debut. The name brings immediate attention because preseason appearances are often where coaches look for how quickly a player can apply training-camp concepts in live, game-like situations. For Seattle, the practical focus is simple, whether Diggs can translate practice reps into coverage instincts, communication, and consistency under tempo.

The preview also pointed to extensive attention on Jalen Milroe, with the wording emphasizing “lots of” him. That matters because quarterback reps in the final week of the preseason often become the clearest indicator of who can command a rhythm while moving through multiple looks. It also gives the staff a way to evaluate decision-making under pressure, including how a quarterback handles protections, reads the defense quickly, and manages the details of timing within the play-call.

Beyond the marquee mentions, the Seahawks’ preview highlighted the broader theme of competition. Preseason finales tend to compress the timeline for players on the fringe, since the regular-season roster cut and preparation cycle accelerates after the final game. The Seahawks are using the Kansas City trip as a capstone for those evaluations, essentially asking players to show they are ready now, not later.

For fans, this kind of game can look like a collection of auditions, but the underlying emphasis is on roster construction and role clarity. Coaches use the closing preseason week to tighten assignments, confirm how units communicate, and determine which players consistently do what the playbook expects when the opponent is pressing and the execution window is smaller.

Seattle’s staff also benefits from a regular-season rehearsal dynamic. Even when starters do not play extensive minutes, preseason finales can still reveal who is prepared for the speed of the NFL, including how well players adjust on the fly, maintain spacing, and respond to formations and pressure packages they see in real time.

What to watch next is less about predicting outcomes of specific matchups and more about who takes control of the narrative in live action. If Diggs’ debut shows him fitting into Seattle’s defensive structure quickly and Milroe’s reps demonstrate command of the offense’s timing and decision-making, it gives the Seahawks clarity heading into the regular-season opener. If either does not, the preseason finale still accomplishes its purpose by surfacing what needs to be corrected before the games count.

For all the evaluation, it is also important to remember that preseason games can be uneven by design, with rotating personnel and different usage patterns. The Seahawks’ preview underscores that this is the end of the preseason process, so the most meaningful takeaway will be how consistently players perform within the role the staff is trying to build.
