Dolphins 90 in 90: Breaking down Seth Coleman’s roster position

Our Miami Dolphins offseason roster breakdown continues this afternoon with a return to the team’s edge rushers. This series takes a player-by-player look at Miami’s roster, breaking down their biographical information, their current contract, how they played in 2025, roster moves the team has made this offseason, and what the player’s role in 2026 might be.

Among the edge rushers, we have already looked at undrafted free agent rookie Mason Reiger and free agent signing Josh Uche. We return to the position group with a look at a 2025 undrafted free agent who did not qualify for a year of service. Seth Coleman is still considered a first-year player as he looks to find a way onto the Dolphins’ regular-season roster.

Coleman signed as an undrafted free agent with the Seattle Seahawks after the 2025 NFL Draft, spending training camp and the preseason with the team. He was among the team’s final round of roster cuts in August. He signed with the Indianapolis Colts, joining their practice squad, in October, but was released less than a week later. He remained out of football until the Dolphins signed him to a reserve/futures contract after the season.

Defensive end signings: Robert Beal, Jr., Seth Coleman, Cameron Goode (re-signed), Rodney McGraw (UDFA), David Ojabo, Mason Reiger (UDFA), Josh Uche

Released: Bradley Chubb, Derrick McLendon (waived)

Drafted: Trey Moore (4th round), Max Llewellyn (7th round)

Primarily playing as a rush linebacker at Illinois, Coleman proved he has the potential to make it at the NFL level, likely working as a rotational player with special teams responsibilities. In Miami, he will likely have to adjust to playing with his hand in the dirt as a 4-3 defensive end. If he can make an impact in camp and the preseason, Coleman could fight his way onto the 53-man roster as a depth option if needed, but it is a massively uphill battle.

Coleman is most likely a camp body who is battling to make the practice squad when the season starts.
