Dolphins 90 in 90: Seth Coleman’s edge-rusher path as Miami looks for a roster break-through

Miami’s offseason roster work continues with a position-specific focus on the Dolphins’ edge rushers, and one name that stands out in that group is Seth Coleman. The storyline is straightforward: Coleman is trying to convert a year of bouncing around as an undrafted free agent into something more stable, a rostered role that lasts beyond the early phases of training camp and preseason.

In the Dolphins’ “90 in 90” series, the team frames this chapter around Coleman’s roster position heading into camp. The central premise is that, in 2026, Coleman is seeking a clearer job in Miami’s defensive front. For a player who entered the league outside the draft, that shift often depends on turning practice reps into consistent role-specific production, while also showing the coaching staff that he can be counted on in the team’s defensive system week to week.

Coleman’s situation also reflects a common NFL pipeline reality. Undrafted players frequently spend a stretch moving between opportunities, looking for the right fit, then trying to demonstrate that they can hold a job once training camp gets tight. Miami’s offseason attention to the “edge” group suggests the club values adding and developing depth at the outside pass-rush spots, where matchups and situational usage can widen the margin for a fringe player to earn reps.

The edge rushers in Miami are more than just standalone athletes. They are expected to contribute across a range of roles, including base defense responsibilities, passing downs, and scenarios that require discipline and leverage. For Coleman, the challenge is not only to get to the quarterback, but to do it within the Dolphins’ defensive structure, where assignments and technique consistency matter as much as raw burst. The “90 in 90” format underscores that the organization’s evaluation will include how Coleman fits within Miami’s plan for the coming season.

Because the item is a roster breakdown leading into training camp, it naturally frames Coleman’s 2026 outlook in terms of opportunity rather than certainty. It positions him as a player who, after time spent pursuing a foothold, now needs to show that he can separate from the pack in a crowded group. That separation is usually earned through repeatable traits at practice and the ability to make plays when given limited windows in preseason work.

What to watch next is how Coleman’s camp reps shape the Dolphins’ sorting process along the edge. If the staff can see a stable role for him, Coleman becomes a depth asset with potential matchup value. If he cannot, the Dolphins’ edge rotation likely continues to lean heavily on established players and other camp tryouts. Either way, the series makes the immediate stakes clear: Coleman’s path in 2026 is about converting an unsettled entry into the league into a roster position that can survive the final cuts.
