The reported list of Miami Dolphins undrafted rookie signings has several underdogs who could claim a 53-man roster spot in 2026
Which reported undrafted rookie signing from the 2026 NFL Draft has the best chance to make the Miami Dolphins’ 2026?
The size of the Miami Dolphins‘ 2026 NFL Draft class creates limited opportunities for undrafted rookie players to come in and make an impact. With a baker’s dozen of draft choices already in hand, Miami’s offseason roster has pushed towards maximum capacity.
Several undrafted players have, however, agreed to join the Miami Dolphins. Which one has the best chance of making Miami’s 53-man roster in 2026? Here’s a few standouts and which one should be considered the favorite.
Which Miami Dolphins 2026 undrafted rookie has the best chance to make the 53-man roster?
QB Mark Gronowski, Iowa Hawkeyes
Gronowski’s going to be battling for the QB3 role in Miami behind Malik Willis and Quinn Ewers. His primary competition is Cam Miller, who the Miami Dolphins signed at the end of last season. Miller spent his rookie season with the Las Vegas Raiders.
Here’s the issue. Even if Gronowski wins the QB3 spot, there’s a chance Miami only keeps two quarterbacks on the 53-man roster. He feels like a long-shot for more ways than one.
RB Le’Veon Moss, Texas A&M Aggies
The running back position is pretty full for the Dolphins, as the team boasts De’Von Achane, Ollie Gordon II, and Jaylen Wright in front of Moss. Moss has enough talent to be drafted — but durability has been a pain point for his college career. Should the Miami Dolphins find a transaction for a returning player (unlikely now that the draft has passed), it would open up Moss to have a clear path to earn a spot.
DT Rene Konga, Louisville Cardinals
Konga is the most athletically gifted player among this group. He has dynamic testing numbers from his Pro Day and you see the twitchiness on film. The issue for Konga is that the high-level moments on tape are a bit too irregular. It will be the job of defensive line coach Austin Clark to establish enough rapport and growth with Konga between now and cutdowns at the end of the preseason.
Konga’s position room is a steep challenge, too. Zach Sieler, Kenneth Grant, Jordan Phillips, and Zeek Biggers all feel like players ready to seize parts of the rotation. Will Miami carry 5 or 6 interior defenders? If it’s five, Konga will need to beat out veteran Matthew Butler. If it’s six, I’d say Konga has the best odds of any undrafted rookie to make the team.
EDGE Mason Reiger, Wisconsin Badgers
You’ve seen the pass rush room. Former first-round pick Chop Robinson faces a critical third season with the Miami Dolphins. He’s joined by veteran free agent signings like Joshua Uche, Robert Beal Jr. and David Ojabo — plus two draft choices in Trey Moore (4th round) and Max Llewellyn (7th round).
The competition is wide open, with only Robinson, Moore, and Uche (a guaranteed salary) feeling like locks. Reiger had a strong pre-draft process and shined at the 2026 Shrine Bowl — he’s a leading contender to steal a 53-man roster spot in 2026.
SAF Louis Moore, Indiana Hoosiers
Moore is a compelling name here. He’s not the same athlete as some of the other names in the safety room. But he’s a high-football IQ player whose maturity (he’s 25 years old) helped him seize a key role in Indiana’s National Championship campaign this past season.
The Miami Dolphins safety room is filled with unknowns: veterans Lonnie Johnson and Zayne Anderson join second-year safety Dante Trader Jr., third-year safety Omar Brown, and 2026 fifth-round draft choice Michael Taaffe. There are spots here for the taking and Moore has as good a chance of any undrafted rookie on this offseason roster as a result.
