Chuck Clark, A Proven Leader In The Lions Secondary 

Addressing the leadership that Clark brings, Sheppard highlighted his talent for communicating and ensuring others are properly aligned. Besides knowing his own role, he directs his teammates to make sure they’re in position. 

Talking about Clark, Sheppard stated confidently, “The first word I would say is leader, leader, leader… When Chuck is on the field, you know where the safety is, you know what the check is, and you know what the communication is. And that is vital and important. You talk about explosive plays, well, that is the number one component to limiting those, making sure we are all on the same page…the leadership has been outstanding from that player.”

Roger McCreary Brings Untapped Potential to Lions Secondary  

McCreary, a former second-round 2022 NFL Draft pick from Auburn, had a breakout senior year and was voted First Team All-SEC and First Team AP All-American. He recorded 49 tackles, two interceptions, and his 14 pass defenses led the conference.  After a strong rookie season, McCreary became the starting nickelback for the Titans in 2023, racking up an impressive 86 tackles, 2.0 sacks, six PBUs, one interception, and one forced fumble. However, after he was traded to the Rams in October of 2025, McCreary suffered a hip injury in Week 12 that landed him on injured reserve for several weeks. Returning from injury in Week 17, he was able to take the field for the Rams postseason.  

Speculating who might take over Amik Robertson’s former roster spot, Sheppard singled out McCreary as a strong possibility. “It’s a lot of guys that are in flux, but a guy that’s kinda popped to me early, Roger McCreary has come in and done a great job.”

Christian Izien, A Versatile Proven Talent For The Lions Secondary 

Sheppard noted how having a player who can assume multiple roles in a defense is a tremendous advantage. Former Tampa Bay Buccaneer Christian Izien brings positional versatility, playing both safety and cornerback. When he was in Tampa Bay over the past three seasons, Izien primarily played nickel, but also took on the roles of a box and free safety.

Talking about what a swing player like Izien brings to the defense, Sheppard explained, “He came over here and said, ‘What do you guys need me to play?’ And I said, ‘I might need you to learn two spots,’ and he said, ‘Oh, that would be one less than I had to learn in Tampa because I had to know three.’  

“The adaptability, the adaptability that you have as a coach and player in this League is vital because things are going to change. We are going to have set plans when we are going into Week 1, and probably by the second quarter of the Saints games, something is going to be different than what we thought it was going to be, and in that moment, who are you? And that is what we are going through right now.”

As a defensive back, Izien’s “eye-catching speed and explosiveness,” tackling ability, and his knack for forcing fumbles make him a genuine threat regardless of which position he plays.  Dan Campbell is also a fan of what Izien brings to the Lions’ defense.  Calling him “a headsy player.” Campbell said admirably, “He’s pretty violent. See ball, hit ball.”

Returning Players For The Lions Secondary 

In addition to the newly acquired veteran free agents, the Lions have starting cornerbacks Terrion Arnold and D.J. Reed, along with Ennis Rakestraw and Khalil Dorsey. Last season, Arnold, Rakestaw, Reed, and Dorsey suffered injuries, causing them to miss significant playing time. This year, Arnold faces pending legal issues that may interfere with his availability.

When the Lions’ injury bug decimated Detroit’s entire starting secondary last season, Rock Ya-Sin, Avonte Maddox, Thomas Harper, and Nick Whiteside were the standout reserves who became the next-men-up. Extended during the off-season with a one-year $4 million contract, Ya-Sin is expected to play a larger role this season.  

A Big Opportunity For Thomas Harper On Lions Secondary 

Another player who could see a bigger role this year is returning “Legion of Whom” reserve Harper. Praising his range and ball-hawking ability, Sheppard extolled, “The range of the player, that is kind of his superpower. When you talk about an angel in the outfield, what is the superpower of that player? It’s two things – range and then the ability to do what we call eraser tackle, that’s when the ball pops. In the NFL, the guys in deep, he has got to be able to do those two things – have range and instincts, and then when the ball pops, get the ball on the ground.”

Another returning player who could make a difference is promising second-year player Dan Jackson.  After suffering a serious leg injury during his rookie training camp last year, he missed the entire season.  However, before his injury, Jackson showed promise and could be an impact player for the Lions this season.  

Lions Secondary Rookies 

In addition to the veterans and the returning players, two rookies, Keith Abney II and Aamaris Brown, are among those competing to make the roster out of training camp.  Abney, considered one of the top steals of the 2026 NFL Draft, smashed records as a Junior from Arizona State and received an 86.3 PFF.com on 785 snaps with two interceptions, nine PBUs, and two forced fumbles. He didn’t allow a single touchdown on 72 targets.
