One Dolphins Defender Could Finally Change Everything In Miami's Secondary

The Miami Dolphins are banking on rookie Chris Johnson and a revived JuJu Brents to transform their cornerback struggles and reshape this year's training camp dynamics.

The Miami Dolphins finally made a real investment at cornerback when they took San Diego State’s Chris Johnson with the 27th overall pick in this year’s draft, but the bigger swing for this defense might come from a player who wasn’t supposed to be the headline.

That player is JuJu Brents.

Miami’s cornerback room still has plenty of questions beyond the rookie, and Jason Marshall Jr. is the name most people point to as the potential starter on the boundary opposite Johnson. Marshall got some run as a rookie last season, mostly at nickelback, and the results weren’t especially convincing. So while Marshall is shifting back to his preferred spot, Brents is the one who could end up changing the feel of the whole group.

Brents arrives with a reputation that’s easy to understand and hard to ignore. He’s 6-foot-3, long, physical, and built to bother receivers at the line and at the catch point.

He also comes with the kind of injury history that has followed him everywhere. Through three seasons, he has appeared in only 18 games, and that reality helped derail his time with the Indianapolis Colts after they made him a second-round pick in 2023.

The Colts expected Brents to be part of the answer at corner, but availability kept getting in the way. Miami gave him another chance, and for a stretch he started showing why he was such a well-regarded prospect out of Kansas State. Then another setback hit: a season-ending foot injury in Week 11 cut short what had been a promising sample.

Even with that limited runway, Brents made an impression. Per PFF, he played 66 coverage snaps, was targeted just seven times, and allowed four catches for 29 yards.

That’s the kind of efficiency that jumps off the page, especially for a defender who was tested only sparingly. His busiest day came against the Bills and Josh Allen, when Miami won 30-13 at Hard Rock Stadium and Brents held up well in a game that stood out as one of the few bright spots for the Dolphins as the Tua Tagovailoa-Mike McDaniel era came to a crashing halt.

That’s why Brents feels like the wild card in this camp. Nobody really knows how high his ceiling goes, but the flashes he’s shown in Miami have been more convincing than what anyone else in that cornerback mix has put on tape. If he stays healthy, and if Johnson settles in quickly in his first pro season, the Dolphins could suddenly be looking at a young cornerback duo worth building around.

For a team that hasn’t treated the position like a priority in recent years, that would be a major shift. And Brents is the one with the chance to make it happen.

Jacob Rodriguez May Be Forcing A Dolphins Decision Already

Jacob Rodriguez arrived in Miami with a rsum that already made the Dolphins comfortable spending a second-round pick on him, even with Jordyn Brooks and Tyrel Dodson in place at linebacker. The former Texas Tech standout, a converted quarterback, has been working through the usual rookie transition while also drawing attention for the instincts and playmaking that helped him stand out in college and put him near the top of the national awards conversation.

What has made Rodriguez even more interesting is how quickly he has fit into the Dolphins environment. He has been outspoken about the teams facilities and overall player care, and he and the rest of the rookie class have leaned into the work ethic the staff wants ahead of training camp. For Miami, the bigger question is no longer just how Rodriguez develops, but how soon his presence forces a real decision on the linebacker room. [Read more 🡒]

Dolphins Fans Will Notice Jonah Savaiinaea's Latest Reset

Jonah Savaiinaeas reset comes with a familiar look and a cleaner fit. After Kion Smiths release opened up No. 71, the second-year Dolphins offensive lineman is back in the number he wore before, and it is part of a broader offseason shuffle that has touched several players. Kenneth Grant has moved to No. 78, Ollie Gordon to No. 0 and Storm Duck to No. 29, small changes on paper but the kind of details teams often hope signal a fresh start.

For Savaiinaea, the bigger change is where he lines up. The Dolphins are moving him from left guard back to his natural spot at right guard for the 2026 season, a switch they believe can help him settle in after a difficult rookie year. Miami is still looking for stability up front, and Savaiinaeas return to a more comfortable role is one more attempt to get the offensive line pointed in the right direction. [Read more 🡒]

Dolphins Rebuild Is Drawing Brutal Reviews For One Troubling Reason

The Dolphins spent the offseason trying to reset the roster, but the early outside reaction has been rough. After a flurry of moves that included changing the quarterback picture, reshaping the defense and adding draft picks, one Sporting News analyst still handed Miami a D grade, a sign the rebuild is being viewed as more of a scramble than a clean reboot.

What stands out most in that critique is how thin the margin looks on both sides of the ball. The wide receiver group has been flagged as a problem after the departures at the top of the depth chart, and the defense is still being viewed as unsettled enough to raise doubts about how quickly this can turn around. In that kind of evaluation, even the optimistic path for Miami comes with a warning label. [Read more 🡒]
