Commanders host Dolphins in preseason Week 1 opener as QB3 battle takes focus

The Washington Commanders return to preseason football with Week 1 set against the Miami Dolphins, hosted at Northwest Stadium. After a joint practice earlier this week, the matchup moves from coordinated work to live game-speed evaluation, where every snap carries weight for roster decisions across both teams.

A central storyline for Washington is how the quarterback depth chart looks in this first exhibition. Jayden Daniels is not expected to play in the opening preseason game, shifting early attention to Marcus Mariota as the likely starter. For the Commanders, that also changes the way coaches can evaluate the rest of the quarterback room under game conditions, not just practice reps.

With Daniels expected to remain on the sideline, the competition for QB3 becomes the most immediate job to be done. The preseason opener is framed as the setting where the battle for that third quarterback role takes focus, particularly between Sam Hartman and rookie Athan Kaliakmanis. For Hartman and Kaliakmanis, this is less about a single standout drive and more about demonstrating control, decision-making under pressure, and readiness to be the first option behind the starter.

The Commanders are also approaching the game with plenty of new names in the mix, and the exhibition is expected to function as an extended audition for players trying to separate themselves before the roster trims. In a preseason opener, the evaluation is rarely limited to the headline positions. Coaches typically track command of the playbook, protection reads, special teams readiness, and how quickly players process the rhythm of the game.

For Miami, the matchup offers its own version of the same evaluation process. The Dolphins and Commanders already shared practice time, so the game becomes a different test, focused on execution when tempo, personnel rotations, and game-plan wrinkles shift from team drills to true live downs.

As the first week of the preseason begins, the bigger picture for both clubs is how early indicates translate into the coming weeks. If Hartman and Kaliakmanis draw meaningful opportunities, the Commanders will look for consistency in fundamentals and decision-making rather than chasing highlight moments. In the broader roster chase, Washington will also be watching which new contributors can turn practice effort into reliability when the game clock is running.

What to watch next is whether Mariota’s work provides stability at the top while the coaching staff uses the QB3 snaps as a structured evaluation. If the game offers enough second-and-third-quarter quarterback reps, it should clarify the pecking order for the backup spots and help determine who gets the majority of reps in the next preseason window.
