The Miami Dolphins may have just found a diamond in the rough, and his name is Mason Reger. The undrafted free agent edge rusher out of Wisconsin is turning heads across the NFL landscape, with analysts and scouts alike questioning how a player with his explosive talent slipped through the cracks of the seven-round draft. For a Dolphins team desperate for pass-rushing depth, Reger could be the steal of the offseason.
Reger, who went unselected in the 2025 NFL Draft, was ranked 200th on the consensus big board, a grade that typically warrants a Day Three selection. Analysts like Jordan Reed had him as a top 150 prospect, while Matt Miller and Dane Brugler acknowledged his immense potential. The only reason he went undrafted, according to multiple reports, is a terrifying injury history that includes a bone infection, stress fractures, and a metal rod permanently placed in his shin.
The injury saga began in 2024, when Reger missed the entire season due to a severe knee issue. What followed was a nightmare of complications. He underwent up to six surgeries to recover and rehab, battling a bone infection that kept him sidelined. During rehab, stress fractures in his leg required another surgery, ultimately leading to the insertion of a metal rod in his shin. The medical feedback, detailed in Dane Brugler’s draft guide, painted a picture of a player whose talent was undeniable but whose long-term health was a massive red flag for NFL teams.
Despite the grueling medical history, Reger’s tape from his final season at Wisconsin in 2025 is nothing short of electrifying. He posted a 15.9% pass rush win rate, ranking 26th in college football, and a 23% win rate in true pass rush sets. His 45 pressures were the 31st most in the nation, an impressive feat for a Wisconsin team that struggled mightily on offense. Reger was often the lone bright spot on a defense that faced relentless pressure.

His explosiveness off the line of scrimmage is his defining trait. At the pre-draft process, Reger posted a 9.63 Relative Athletic Score, with a 9.9 grade in explosiveness. He recorded a 40-inch vertical jump and a 10-foot broad jump, numbers that would make any NFL scout salivate. His speed rush accounted for 48% of his pass rush wins, while inside moves made up 40%, and power moves the remaining 12%. When he got to the edge, quarterbacks had every reason to panic.
The Shrine Bowl was another stage where Reger shined. He was named the game’s MVP, showcasing his ability to dominate against competition that included future NFL players. While the Shrine Bowl isn’t the Senior Bowl, being the best player on the field in any postseason all-star game is no small feat. It was a testament to his readiness for the next level, despite the medical concerns that plagued his draft stock.
For the Miami Dolphins, the edge rusher room is a mess. The team’s top pass rusher, Chop Robinson, is entering his third year and needs to prove he can be a consistent force. Beyond him, the depth chart is filled with question marks. Trey Flowers was drafted in the fourth round, but he’s unproven. Veterans like David Ajabu, Cameron Goode, and Derek McClendon have yet to make a significant impact in the NFL. The cupboard is bare, and Reger has a legitimate path to the 53-man roster.
The Dolphins are expected to keep five edge rushers on their initial 53-man roster, based on the tendencies of defensive coordinator Jeff Hafley, who kept five edges in each of his two seasons with the Green Bay Packers. If Miami sticks with that number, only three players are locks: Chop Robinson, Trey Flowers, and veteran Josh Uche. That leaves two spots up for grabs among a group that includes Reger, seventh-round pick Max Lewellyn, and the trio of veterans.
Reger’s competition is stiff, but his upside is unmatched. Lewellyn, a seventh-round pick, is a solid prospect, but he lacks the explosive traits that Reger brings to the table. The veterans, Ajabu, Goode, and McClendon, have had multiple seasons to prove themselves and have failed to do so. If Reger can stay healthy through training camp and the preseason, his tape and athleticism should earn him a spot.
The biggest concern, of course, is his health. Reger’s injury history is not just a minor red flag, it is a massive, flashing warning sign. The bone infection, the stress fractures, the metal rod, all of it raises questions about his durability. But the Dolphins are taking a calculated risk. If Reger can stay on the field, he has the potential to be a rotational pass rusher who can generate pressure at a high level. If he can’t, the team loses nothing, as undrafted free agents come with no guaranteed money.
The Dolphins’ decision to bring in Reger is a reflection of their desperation for edge rushers. The team has struggled to generate consistent pressure off the edge for years, and the current roster offers little hope for improvement. Chop Robinson has shown flashes but has yet to put it all together. Trey Flowers is a developmental prospect. The veterans are journeymen at best. Reger, despite his injury history, offers a skill set that the Dolphins simply do not have elsewhere.
His pass rush win rate of 15.9% is elite, and his ability to win with speed and inside moves makes him a versatile weapon. The Dolphins’ defensive scheme, which relies on pressure from the front four, would benefit greatly from a player who can win one-on-one matchups. Reger’s explosiveness off the line gives him an advantage against slower offensive tackles, and his hand placement and footwork are advanced for a player with his limited experience.
The question is whether Reger can translate his college production to the NFL. His 45 pressures in 2025 were impressive, but he only managed five sacks. That is a concerning trend, as it suggests he struggles to finish plays. Jaelan Phillips had a similar issue last season, generating pressure but failing to convert it into sacks. The Dolphins need a finisher, not just a disruptor. Reger will have to prove he can get the quarterback to the ground.
Another weakness is his missed tackle rate, which was 25% last season. That is far too high for an edge rusher, who must be reliable in run defense. Reger’s aggressive playing style sometimes works against him, as he over-pursues and leaves himself out of position. In the NFL, that will be exploited by savvy running backs and quarterbacks. He will need to refine his technique and learn to balance aggression with discipline.
Despite these flaws, Reger’s energy and leadership are undeniable. Dane Brugler noted in his write-up that Reger’s energy in the locker room and on the field makes everyone around him better. That intangible quality is often overlooked but can be the difference between a player making the roster or being cut. The Dolphins need a spark, and Reger could provide it.
The Dolphins’ front office has a history of taking chances on players with injury concerns. In 2024, they signed cornerback Kendall Fuller, who had a history of concussions, and it paid off. In 2025, they drafted offensive lineman Patrick Paul, who had a torn ACL in college. The team is willing to bet on talent over medical risk, and Reger fits that mold. If he can stay healthy, he could be a steal.
The training camp and preseason will be critical for Reger. He needs to show that his knee is fully healed and that he can handle the rigors of an NFL season. He also needs to prove that his pass rush skills translate against higher-level competition. If he can generate pressure in preseason games, he will force the coaching staff to keep him on the roster.
The Dolphins’ schedule in 2026 includes matchups against some of the best offensive lines in the league. The Buffalo Bills, New York Jets, and New England Patriots all have strong fronts, and the Dolphins will need as many pass rushers as possible. Reger could be a valuable rotational piece, keeping Chop Robinson and Trey Flowers fresh throughout the season.

The undrafted free agent market is often where teams find hidden gems. Players like Cameron Wake, James Harrison, and Arian Foster all went undrafted before becoming stars. Reger has the talent to join that list, but he must overcome his injury history. The Dolphins are betting that his best football is ahead of him, and if they are right, they will have landed a steal.
The pressure is on Reger to perform. He has a chip on his shoulder after going undrafted, and that motivation can be a powerful tool. Players who are overlooked often play with a sense of urgency that draft picks lack. Reger has something to prove, and the Dolphins are giving him the opportunity to do so.
The team’s decision to sign Reger was not without controversy. Some analysts questioned why the Dolphins would invest in a player with such a significant injury history, especially when there were healthier options available. But the Dolphins’ front office believes that talent trumps risk, and they are willing to take a chance on a player who could be a difference-maker.
The Dolphins’ edge rusher room is wide open, and Reger has a legitimate shot to make the 53-man roster. If he does, he will be one of the most intriguing stories of the 2026 season. A player who was once considered a top 150 prospect but fell due to injury, now fighting for a spot on an NFL team. It is a story of resilience, determination, and the power of second chances.
The Dolphins’ fans should be excited about Reger’s potential. He is a player who can generate pressure, disrupt offenses, and bring energy to the defense. If he can stay healthy, he could be a key contributor for years to come. The team’s decision to sign him was a low-risk, high-reward move that could pay off in a big way.

The NFL is a league of opportunity, and Reger is seizing his. He has the talent, the work ethic, and the motivation to succeed. The only question is whether his body will hold up. If it does, the Dolphins will have found a steal in undrafted free agency. If it doesn’t, they will move on and look for the next gem.
The 2026 season is still months away, but the excitement around Reger is building. He is a player to watch in training camp, and his journey from undrafted free agent to potential roster spot is one of the most compelling stories of the offseason. The Dolphins are betting on his talent, and only time will tell if that bet pays off.
For now, Reger is focused on proving himself. He is working hard, staying healthy, and preparing for the opportunity of a lifetime. The Dolphins gave him a chance, and he intends to make the most of it. If he succeeds, he will be a testament to the idea that talent can overcome adversity.
The Dolphins’ edge rusher room is a battleground, and Reger is ready to fight for his spot. He has the skills, the drive, and the determination to make the team. The only thing standing in his way is his own body. If he can stay healthy, he will be a force to be reckoned with.
The NFL is a league of second chances, and Reger is getting his. He went undrafted, but he is not giving up. He is proving that he belongs, and he is doing it the hard way. The Dolphins are lucky to have him, and they know it.
The 2026 season is shaping up to be a defining one for the Dolphins. With a new defensive coordinator and a revamped roster, the team is looking to make a playoff push. Reger could be a key piece of that puzzle, providing the pass rush that the team has been missing.
The Dolphins’ fans should be optimistic about Reger’s potential. He is a player who can make an impact, and he is hungry to prove himself. The team’s decision to sign him was a smart one, and it could pay off in a big way.
The story of Mason Reger is just beginning. He is an undrafted free agent with a dream, and he is determined to make it a reality. The Dolphins gave him a chance, and he is ready to seize it. The 2026 season cannot come soon enough.
