Dolphins-Commanders Preseason Recap: What Miami and Washington Learned in Week 1

Washington beat Miami 20-7 in both teams' preseason opener on Friday, August 14, and almost none of it involved the players either fan base actually cares about. Jayden Daniels, Terry McLaurin, Stefon Diggs and roughly two dozen other Commanders starters and rotation regulars sat out entirely, and Miami's own top skill players played a series or two at most. What was left was a backup-heavy roster evaluation game, and it produced three real fantasy storylines: an undrafted running back nobody outside Washington's building had heard of two weeks ago, a backup quarterback injury that thins out the Commanders' QB2 picture behind Daniels, and a rookie Miami receiver who is already the best story on that offense.

Washington's crowded backfield got even more crowded

Kaytron Allen

Kaytron Allen, Washington's sixth-round pick out of Penn State (No. 187 overall), scored on a short touchdown run in the second quarter after taking over on the ground once Marcus Mariota left the game. Allen leaves Penn State as the program's all-time leading rusher, and NFL.com's pre-draft scouting had him pegged as a between-the-tackles grinder without much explosive ability, so a touchdown in a low-event preseason opener is a reasonable start to proving that profile out at the next level.

He was not the best back on the field, though. That was Robert Henry Jr., a UTSA product who joined the roster as an undrafted free agent this spring after totaling 1,045 rushing yards and nine touchdowns on 151 carries as a senior. Henry ran for a 22-yard touchdown and was the most explosive ball carrier in the building all night. Riggo's Rag called it the performance that left the coaching staff with an unexpected roster problem, and that tracks: an undrafted rookie outrunning a drafted rookie and the incumbent depth backs in the same game is exactly the kind of night that turns a camp body into a real 53-man roster conversation.

Marcus Mariota's night, and Washington's backup QB picture

Marcus Mariota

Mariota started in place of the rested Daniels and lasted four offensive plays before going down with a non-contact leg injury while handing the ball off, later diagnosed as a sprained MCL that is expected to keep him out for the rest of the preseason. That is a real problem, since Mariota was the presumptive QB2 behind Daniels for the regular season, not just a camp arm.

With Mariota out, backup Sam Hartman took the bulk of the second-half snaps and settled in after a shaky start, moving the offense with completions to receivers Jaylin Lane and Van Jefferson on scoring drives. None of that changes what Daniels does on Sundays, but it does mean the coaching staff needs Mariota's MCL to heal cleanly before Week 1 of the regular season, or the emergency-QB plan behind Daniels gets thinner than it was a week ago.

Caleb Douglas gives Miami's offense a bright spot

Miami's lone highlight of the night came on the opening drive: Malik Willis led a 14-play, 93-yard march that De'Von Achane finished with a short touchdown run, and Willis found third-round rookie Caleb Douglas for a 28-yard gain on a one-handed grab along the way. Douglas, the No. 75 overall pick, was already the most talked-about training camp performer on the roster heading into the game, landing a starting outside receiver spot on the team's first depth chart alongside Malik Washington and Jalen Tolbert despite being viewed as a reach when he was drafted. A real catch like that against a game rotation of backup defensive backs is a small sample, but it is the kind of moment a third-round rookie needs to hold that starting job once camp bodies get cut down.

Miami did not sustain much after that. Quinn Ewers took over at quarterback and threw an interception, and the offense that produced a 14-play touchdown drive to open the game did not find that rhythm again the rest of the night.

What to make of the rest of the depth chart

The players fantasy managers actually roster, Daniels, McLaurin and the newly signed Diggs among them, told you nothing new on Friday because none of them played. That is standard for a preseason opener and does not change anything about how Washington's real offense projects. What did change is the shape of Washington's backup QB room behind Daniels and the bottom of its running back depth chart, and Douglas gave Miami one legitimate reason for optimism on a night that otherwise did not have many. None of this moves the needle on Daniels, McLaurin or Diggs, whose actual roles get settled in real games starting in September, not in a 20-7 preseason opener.

If you're stress-testing rookie value ahead of best ball season, Douglas and Allen are both worth a look on the rookies page, where profiles like theirs get updated as camp battles resolve. And if a preseason storyline like Henry Jr.'s makes you want to see how a deep-league flier changes a build, run it through the best ball tools before your next draft rather than guessing at his value off one exciting Friday night.
