Miami Dolphins Coach Jeff Hafley Justified in Resting Starters Amid Roster Thinness

Miami Dolphins coach Jeff Hafley sat out his starters in the team's third preseason game against the Atlanta Falcons — a decision that makes sense given the roster he inherited. Spotrac reports the Dolphins have one of the thinnest rosters in recent NFL history, with $179.9 million in dead cap money (the highest in the league) eating up cap space for players no longer on the team.
The active roster costs just $148.6 million, ranking 32nd in the NFL. Add in rookie linebacker Trey Moore's injury, and Hafley's caution in the preseason becomes justified. The real problem isn't Hafley's coaching — it's the front office mess left behind by ex-GM Chris Grier and current GM Jon-Eric Sullivan.
The Dolphins are drowning in dead cap. Spotrac data shows $179.9 million tied up in players who aren't even on the roster anymore — the worst in football. This leaves Hafley with limited ammunition to build a competitive team. The active roster, at $148.6 million spent on players actually playing, ranks dead last in the league at 32nd. That's a recipe for losing.
These financial constraints aren't accidents. They're the result of years of questionable moves by the front office. Grier made expensive signings that didn't pan out. Sullivan now inherits the wreckage. Hafley, as a new coach, is left managing a team that can't afford to compete until at least 2028.
In the preseason, every snap matters when your roster is this thin. Hafley resting starters against Atlanta protects his limited depth from injury. One more starter going down could cripple the entire season. Moore's injury to the linebacker group already signals how fragile this team is. Preseason games are dress rehearsals, not regular-season battles that demand full effort.
Smart coaches manage risk in August. Hafley is doing his job by keeping his core players healthy for the games that actually count. Fans may want to see the best players perform in the preseason, but that's a luxury a depleted roster can't afford.
Hafley didn't create the Dolphins' salary cap nightmare. Grier, who served as GM before Sullivan took over, signed players to deals that crippled the team's future. Sullivan inherited this toxic situation and is now trying to salvage a franchise in cap purgatory. Until the dead cap money dries up, the team will struggle to add talent or spend wisely.
The playoff window won't reopen until 2028 at the earliest. By then, current stars may have aged out or demanded trades. Hafley is managing expectations and protecting bodies because that's all he can do with the hand he's been dealt. The blame falls on the executives who built this broken roster, not the coach trying to survive it.
