The Detroit Lions haven’t made a big splash in free agency this spring, but their moves have still spoken volumes. While the game plan has been to return to their physical roots with key signings on the offensive and defensive lines, their secondary remains a big problem, especially with third-year cornerback Terrion Arnold.
The 2024 first-round pick has had a rough acclimation to the NFL and didn’t take the leap many were expecting last season. Despite the struggles, defensive coordinator Kelvin Sheppard continues to praise Arnold’s potential and expects him to rise to the challenge during the 2026 season.
“I need him to be quiet and just play,” Sheppard told reporters, via SI’s John Maakaron during February’s scouting combine. “...He wants to be great. But I told him there it’s a difference in talking about being great and actually being great. And he’s starting to understand that.”
While Sheppard’s comments carry weight, the Lions haven’t added additional pressure by adding a cornerback in free agency. Although that could come in the draft, Detroit appears to be banking on Arnold to realize his potential, which could come back to haunt them as they look to get back to contention.
Terrion Arnold on Thin Ice Entering Critical Season in Detroit
Arnold was viewed as a potential long-term starter at cornerback when he was selected with the 24th overall pick in the 2024 draft. But since then, Arnold hasn’t slowed down opposing receivers. According to Pro Football Focus, Arnold allowed 60 catches for 792 yards and four touchdowns on 98 targets during his rookie season. While he improved on his coverage numbers, allowing 23 catches for 331 yards and two touchdowns with an interception, a shoulder injury limited him to just 312 defensive snaps and hampered him throughout the year.
It should also be noted that Arnold has more penalties (16 total, three declined) than interceptions (1) and pass breakups (13) combined through his first two seasons. An ongoing legal situation is also lurking over Arnold. The Lions don’t seem concerned about any of that, though, as Brad Holmes told reporters on Wednesday, “there are no updates” on Arnold’s situation and that it doesn’t have “anything to do with how they’ll draft,” according to Mike Payton of A to Z Sports.
Still, the Lions should probably have a contingency plan if Arnold’s legal troubles take an unexpected turn or if he underperforms for the third straight season. D.J. Reed was effective when on the field, but a hamstring injury limited him to 11 games last season and could inspire the Lions to draft his eventual replacement. Ennis Rakestraw Jr., who was taken one round behind Arnold in 2024, also has the coaching staff's faith to play outside, but he has also dealt with a laundry list of injuries.
Free agent addition Roger McCreary is better suited in a slot corner role than on the outside, and Rock Ya-Sin, Khalil Dorsey, and Nick Whiteside are replacement-level players who could be overexposed if called upon due to injury or poor performance.
In many ways, Arnold will be playing for his future in Detroit next season. But for a Lions team with Super Bowl aspirations, they’ll need him to step up or risk another year wasted in their championship window.
