Broncos' Defensive Line Faces Uncertainty Beyond 2025

The Denver Broncos’ defensive line stands as one of the team's current strengths heading into the 2025 NFL season. However, this positional group could quickly transform into a liability as the team faces a potential mass exodus in free agency. With three of the Broncos’ top four defensive linemen—Zach Allen, John Franklin-Myers, and Malcolm Roach—set to hit free agency after the season, the team’s future up front is filled with uncertainty.

Zach Allen, a key piece on the line, is currently under contract, but that deal voids on February 20, 2026. If not extended before that date, the Broncos would incur over $12 million in dead cap space. Meanwhile, Franklin-Myers and Roach are both in the final year of their contracts. Denver has taken steps to prepare for potential losses by drafting Sai’vion Jones in the third round and bringing back veteran D.J. Jones, but their current depth is not sufficient to replace three starters. Sai’vion Jones may develop into a capable starter, particularly as a 4i/5-technique, mirroring Franklin-Myers’ role. However, defensive linemen often take multiple seasons to adjust to the NFL, making immediate production a gamble. Denver cannot rely solely on one rookie to absorb the responsibilities of multiple veterans. In an ideal scenario, the Broncos would extend both Allen and Franklin-Myers. A three-year deal for Franklin-Myers, including two years of guaranteed money and an optional third year, would provide flexibility and stability. Roach, while not a marquee name, plays a unique role as a pass-rushing nose tackle—a position in short supply across the league. Losing him would force Denver to search for a rare type of replacement. What makes the situation even more precarious is the lack of internal options.

The current roster lacks proven depth behind the starting unit, and without timely extensions or new additions, the Broncos risk entering the 2026 season with holes across the line. If Denver allows these players to walk, they will likely need to invest either a high draft pick or significant cap space to repair the unit—moves that could limit flexibility in addressing other roster needs. Continuity and chemistry are critical along the defensive line, especially in schemes that require complex stunts and gap discipline. The Broncos risk undoing progress made this season if they fail to retain their top contributors. The front office must act decisively to prevent a key strength from becoming a glaring weakness.
