The Miami Dolphins are deep into a roster reset, and that means the front office still has some holes to patch before the offseason is done. One of the clearest ones sits at cornerback, where Miami could use another body with real upside.
That’s why Trevor Diggs has surfaced as a name to watch. Moe Moton of Bleacher Report pegged the former Cowboys and Packers corner as a “bargain bin” free-agent fit for Miami, and the idea makes sense on paper.
“Once a ball hawk in the Cowboys ' secondary, Diggs can rediscover his tip-top form if healthy ahead of the 2026 term,” Moton writes. "... Potential suitors: Detroit Lions, Miami Dolphins."
For a Dolphins team that is not expected to be a playoff contender in 2026, there’s more room to take a swing on a player with a little volatility. Miami already showed that kind of thinking with Malik Willis, and Diggs would fall into that same buy-low, high-upside lane.
The need is real, too. Chris Johnson, one of Miami’s 2026 first-round picks, is in the starting mix, but the rest of the cornerback room is full of names without much certainty.
JuJu Brents, Jason Marshall Jr., Ethan Robinson, Darrell Baker Jr., Storm Duck, Alex Austin, Marco Wilson, Ethan Bonner, A.J. Green III, and Miles Battle are all part of the current group.
Diggs could immediately compete for the nickel job, and at minimum he’d give the Dolphins another experienced option. The 27-year-old was once a Pro Bowl and All-Pro corner, and his peak still stands out: in 2021, he had 11 interceptions, including two pick-sixes.
The downside is obvious. Diggs allowed a 154.2 passer rating last season between the Cowboys and Packers.
But the broader track record is what makes him interesting. Over the five seasons before 2025, he posted a 72.9 passer rating allowed, which is the kind of number a team can talk itself into.
He also shouldn’t cost much. Diggs still doesn’t have a home, and a one-year prove-it deal looks like the most likely outcome.
Miami would also be bringing him into a defense under Jeff Hafley, whose Packers unit took a shot on Diggs last season. It didn’t fully click, but the Dolphins can point to the fact that Diggs had an 81.2 passer rating allowed in one game there, a sharp improvement from the 157.2 passer rating allowed with the Cowboys.
Put it together, and the fit is easy to see: the Dolphins need corner help, Diggs needs a landing spot, and a short-term deal could make sense for both sides.

Dolphins May Finally Have A True WR1 Path In 2027
The Dolphins wide receiver room has lost a lot of its established punch since Tyreek Hill and Jaylen Waddle moved on, and that has left Miami looking ahead for a cleaner path back to having a true No. 1 option. The 2027 free-agent market is starting to look like the kind of place where a team can reset its passing game, especially if a proven receiver shakes loose at just the right time.
Puka Nacua is among the names to watch, with George Pickens and Chris Olave also in the conversation if their situations line up the right way. Michael Wilson has even emerged as another possible option after his breakout in Arizona, which gives Miami a few different routes to explore, but each one depends on contract timing and health holding up between now and then.

Cardinals Already Have An Early QB Problem They Cannot Ignore
Quarterback uncertainty is already part of the conversation for Miami, where Malik Willis has been floated as one of the more vulnerable passers heading into 2026. The attraction is easy to see: he still has a thin rsum, and the Dolphins have a younger option waiting in Quinn Ewers if the veteran-to-be does not settle in quickly.
The larger point is that this kind of list says as much about team planning as it does about the player himself. Miami does not have the luxury of ignoring a position that can tilt a season, and Willis limited experience keeps the pressure on every snap while the club weighs how much patience it really wants to show.
