The Lions don’t just need depth opposite Aidan Hutchinson—they need a true disruptor. Veteran D.J. Wonnum brings stability, but rookie Derrick Moore brings juice. And this camp battle could define Detroit’s pass rush.
There are going to be several intriguing camp battles for the Lions this summer, but few carry as much long-term importance as the edge rusher spot opposite Aidan Hutchinson. Detroit has made it clear they’re not just looking for depth—they’re searching for a true difference-maker who can consistently win one-on-one matchups and prevent offenses from keying entirely on Hutchinson. That’s what makes the battle between rookie Derrick Moore and veteran D.J. Wonnum so compelling. It’s not just about who starts in Week 1—it’s about whether the Lions have finally found a legitimate second pass-rush threat or if they’ll once again be piecing it together with rotational production.
Derrick Moore: The upside swing Detroit needs
Moore brings exactly the kind of profile Detroit has been missing. His 2025 production and efficiency suggest a player who isn’t just productive—but disruptive on a per-snap basis. With 11 sacks, 41 total pressures, and an elite 92.4 pass-rush grade, he was one of the most effective edge defenders in college football despite playing just 440 snaps.
What stands out most is how translatable his game is. At 6’4” with long arms and a strong frame, Moore fits the physical mold Detroit prioritizes. He can set the edge in the run game while still offering legitimate juice as a pass rusher—something this defense has lacked outside of Hutchinson.
There’s also the mentality piece. Moore was a team captain and one of the most relentless defenders on his unit. That aligns closely with the identity Detroit has built under Kelvin Sheppard—physical, aggressive, and effort-driven.
The key factor: he doesn’t need high volume to produce. His pressure rate and efficiency suggest that if his snap count increases, the production could scale with it.
D.J. Wonnum: Stability and experience
Wonnum represents the opposite end of the spectrum. He’s a known quantity—a six-year veteran who has started 54 games and consistently stayed available. After dealing with injuries along the defensive line the past two seasons, that reliability alone has value.
He’s also scheme-versatile. Having played in both 4-3 and 3-4 looks, Wonnum can line up with his hand in the dirt or stand up, which gives Detroit flexibility depending on the front they want to show.
But when you dig into the numbers, the limitations become clear. Over the past two seasons, his pass-rush production has been below average compared to starting-caliber edge rushers. His 2025 PFF grades (49.9 pass rush, 54.7 overall) reflect a player who isn’t consistently winning his matchups.
That doesn’t make him useless—it just defines his role. He’s more of a steady, assignment-sound defender than a player offenses have to game plan around.
Fit within Detroit’s defense
The Lions don’t just need someone to “hold down” the opposite edge—they need someone who can change the math for opposing offenses. Hutchinson already commands attention. Without a legitimate threat across from him, offenses can slide protection, chip, and neutralize Detroit’s biggest weapon.
* Wonnum helps keep things functional
* Moore has the potential to tilt the field
That distinction matters.
Who’s the better fit?
Early in the season: Wonnum likely gets the nod
* More experience
* More reliable in assignments
* Lower risk while Moore adjusts
As the season progresses: Moore should take over
* Higher ceiling
* More explosive pass-rush ability
* Better fit for what Detroit ultimately needs
If Moore develops the way his college production suggests, it won’t take long for the coaching staff to justify increasing his role.
Final takeaway
D.J. Wonnum gives Detroit a safety net.
Derrick Moore gives them a potential solution.
And if the Lions are serious about elevating their defense from solid to dangerous, Moore is the player who can make that leap happen.
