Among the free agency decisions awaiting Brad Holmes is addressing the Detroit Lions’ battered secondary. Losing all three starters, Terrion Arnold, Kerby Joseph, and Brian Branch, to season-ending injuries proved devastating. Unfortunately, a great deal of uncertainty surrounds their anticipated return dates. Consequently, one free agent the Lions should retain is cornerback Rock Ya-Sin.  

Making The Case For Detroit Lions To Re-sign Rock Ya-Sin 

Last season, Ya-Sin was brought in as added depth after Holmes signed D.J. Reed to a splashy four-year $48 million contract. Positioned on the depth chart behind Arnold, Reed, and Amik Robertson, the NFL veteran wasn’t expected to be a starter. 

However, due to the avalanche of secondary injuries, Ya-Sin appeared in all 17 games and wound up starting six. He gave up just one touchdown in his coverage area with a 51.9 completion percentage and a 74.7 passer rating against. Ya-Sin finished the year with 45 tackles (36 solo), nine pass defenses, and three pressures. However, his stats don’t reflect the entirety of his contribution. Ya-Sin impressed Dan Campbell and the Lions coaching staff as a reliable, important part of the Lions’ secondary.   

While Lions‘ DC Kelvin Sheppard has expressed a clear preference to have Ya-Sin deployed at the outside corner, his ability to play both cornerback slots as well as safety speaks to his athleticism and high football IQ. Praising Ya-Sin’s toughness and durability after briefly leaving a game with cramps, Campbell stated afterwards, “I like Rock. We all like Rock. His work ethic, man. He’s pretty tough, he’s physical, he’s headsy, and he’s versatile.” 

Ya-Sin Career Overview 

As an experienced seven-year NFL veteran, Ya-Sin brings a solid perspective and understanding of his role and value to the team. Selected by the Indianapolis Colts in the second round with the 34th pick of the 2019 NFL Draft, he had stints with the Las Vegas Raiders, Baltimore Ravens, and the San Francisco 49ers before Detroit. With 231 career tackles (179 solo), 40 pass defenses, and two interceptions, Ya-Sin shows no signs of slowing down. His nine PDFs this season exceeded his previous career mark of eight, in 2021 with Indianapolis.  

Ya-Sin’s most controversial play this season was a pass interference penalty against A.J. Brown of the Philadelphia Eagles that proved to be an erroneous call. Since P.I. calls aren’t subject to replay, the penalty stood. Afterwards, Campbell defended Ya-Sin’s coverage of Brown, “Yeah, well, I thought he played defense like he did the whole game, man. I thought he challenged and played it like he did the very first rep that we played man-to-man. So I wouldn’t tell him to do anything different, man, get up there and challenge. Play your style, and that’s it.”

Ya-Sin, Outlook for 2026

Ya-Sin is positioned well among others on the Lions’ cornerback roster. At age 29, he’s the same age as Reed and younger than 32-year-old Arthur Maulet. Reportedly progressing well from shoulder surgery, Arnold is expected back by the beginning of the season. However, the same can’t be said for Branch or Joseph. The typical recovery time frame for a ruptured Achilles tendon is 10-11 months, meaning that Branch likely won’t return until mid-season. Joseph’s time frame is murkier since little has been said about the nature or extent of his knee problem. 

The decision to re-sign Ya-Sin feels like an easy one. Last year, his contract carried a one-year salary cap hit of $1.17 million. Retaining an experienced player who is already familiar with the Lions’ defense and a great fit for the team can be a cost-effective solution to bolstering the Lions’ secondary.
