No matter what happens in court, the Lions have a major problem to solve—and Rock Ya-Sin may be the biggest beneficiary.
Terrion Arnold’s preliminary hearing set to begin Monday, the Detroit Lions find themselves in a difficult position regardless of the legal outcome. Even in the best-case scenario, if Arnold remains with the team, he could still face a lengthy NFL suspension under the league’s personal conduct policy. That uncertainty has already forced Detroit to prepare for life without its projected starting cornerback, opening the door for another player to seize a significant role.
During mandatory minicamp, veteran Rock Ya-Sin and third-year cornerback Ennis Rakestraw Jr. took first-team reps in Arnold’s absence. While Rakestraw remains an intriguing young option, Ya-Sin appears to be the favorite to start opposite newly acquired cornerback DJ Reed if Arnold is unavailable when the regular season begins.
Rakestraw has appeared in just eight games over his first two NFL seasons and is still developing after injuries limited his early career. Although the Lions remain high on his long-term potential, relying on an inexperienced player to step into a full-time starting role could be a risk.
That makes Ya-Sin one of the most important depth pieces on Detroit’s roster.
Originally selected by the Indianapolis Colts with the 34th overall pick in the 2019 NFL Draft, Ya-Sin spent three seasons in Indianapolis before making stops with the Las Vegas Raiders, San Francisco 49ers, and Baltimore Ravens. He joined the Lions last season and provided valuable depth in the secondary, appearing in all 17 games while making six starts.
Throughout his NFL career, Ya-Sin has started 45 games and recorded two interceptions, 40 pass breakups, two forced fumbles and 246 total tackles. While he has never developed into a shutdown corner, he has consistently proven capable of contributing as a reliable starter when called upon.
According to Pro Football Focus, Ya-Sin earned a 62.8 overall defensive grade during the 2025 season, ranking 57th among 114 qualified cornerbacks. His 64.8 coverage grade ranked 50th, while his 50.8 run-defense grade ranked 87th at the position. He did not record an interception but finished with five pass breakups, allowed a 77.7 passer rating when targeted and surrendered 27 receptions in coverage. He also added 36 solo tackles in run support.
Those numbers represented a noticeable improvement from the previous season. In 2024, Ya-Sin played just 63 defensive snaps and finished with a 44.2 overall PFF grade and a 50.3 coverage grade while allowing only one reception in limited action.
His 2023 campaign was more representative of a rotational role, as he logged 279 defensive snaps, earned a 63.3 overall grade and a 63.8 coverage grade while allowing 11 receptions.
The highest-graded season of his career came in 2021 with Indianapolis. That year, Ya-Sin posted a 69.9 overall PFF grade and an impressive 72.4 coverage grade while allowing 26 receptions across 592 defensive snaps.
Now, Detroit may need him to return to that level of play. With Arnold’s future uncertain and the Lions aiming to compete for a championship, Ya-Sin could once again find himself in a full-time starting role. For the first time since his rookie season, he has a legitimate opportunity to start double-digit games and play a major role for Detroit.
