Lions May Have An Answer To Their Cornerback Problem

With a shallow cornerback roster and a potential trade partner in the 49ers, the Detroit Lions may look to bolster their secondary by acquiring promising talent from San Francisco's deep lineup.

The Detroit Lions’ cornerback room took a hit this offseason, and that has opened the door to a possible trade target from one of the league’s deeper secondaries.

Terrion Arnold, the team’s first-round pick in the 2024 Draft, was cut after an offseason incident saw him arrested on allegations of involvement. That leaves Detroit thinner at corner than it expected to be heading into the 2026 NFL season.

D.J. Reed is back as the top option, but the options behind him are far less settled.

Rock Ya-Sin held up when called on last year, though there are real questions about whether that level of play would hold over a full season in a starting role. Ennis Rakestraw has also battled injuries through his first two NFL seasons.

Beyond that, the group includes Roger McCreary, who could be headed for the nickel spot, along with rookie Keith Abney II and special teams ace Khalil Dorsey.

That situation could push the Lions toward a free agent move or a trade, and the San Francisco 49ers are one team that may have the kind of depth Detroit needs.

The 49ers have Deommodore Lenoir starting on one side, and they’ve also added free agents Jack Jones and Nate Hobbs. Because of that, some analysts believe 2024 second-round pick Renardo Green could be available if San Francisco decides to move him.

The 49ers also added another corner in the 2026 NFL Draft, taking former Washington Huskies defensive back Ephesians Prysock.

Green has played in 31 games over two seasons with San Francisco and has made 21 starts. He has 23 passes defensed and posted a Pro Football Focus defensive grade of 54.3 in 2025.

When he came out of Florida State in 2024, Green looked like a natural fit for Detroit because of the amount of man coverage he played and the way the Lions like to line up defensively. Draft analyst Lance Zierlein labeled him a "pure press-man corner," and that description lines up cleanly with what the Lions want.

There’s also a path where Green is squeezed out of a starting job by San Francisco’s new additions, which would make a trade more realistic. Detroit has the cap room to absorb the remaining two years of his rookie deal, and that matters because Green would not be a one-year fix.

He could grow into the role over the next two seasons, and if the 49ers are willing to move him, he looks like the kind of answer the Lions need to steady a shaky cornerback group. With San Francisco’s depth, a mid-round draft pick could be enough to get a deal done, giving Detroit a corner with experience, upside and a chance to compete for a starting job right away.

These Lions Depth Names Suddenly Feel Far Less Safe

The Lions back end of the roster is starting to look a lot less settled as the team turns its attention toward 2026, and that matters because the margins are where depth charts are won and lost. In a group of players sitting in the 60-to-51 range on the current projection, there are familiar names mixed with newer faces, and the common thread is simple: recent production, special teams value and positional flexibility are going to decide who sticks around.

For players like Jacob Saylors and Tom Kennedy, the appeal is obvious because both have already shown they can help in the kicking game, while Nick Whiteside is trying to turn a late-season flash into something more durable. Even the young linemen and defensive depth pieces in this tier are feeling the pressure of a roster that keeps adding competition, which is why this part of the list reads less like a formality and more like an audition that could still go a few different directions.

Sam LaPorta Just Put Lions Fans In A Tough Spot

Sam LaPortas name still carries plenty of weight around the league, even after a season that ended far earlier than anyone in Detroit wanted. In ESPNs recent survey of executives, coaches and scouts, the Lions tight end was ranked No. 4 among NFL tight ends, a reminder that his impact has stretched well beyond the box score and into the way opponents have to account for him.

What makes that placement especially notable is how efficient LaPorta was when he was on the field in 2025. His yards after the catch and catch rate were among the best at the position, which only adds to the frustration of seeing his year cut short. Dan Campbell said LaPortas rehab is moving in the right direction and that he should be available for training camp, which gives Detroit a reason to feel better even as the bigger question lingers.
