Jack Campbell Metrics: How Lions LB Is Dominating NFL in 2026
Jack Campbell is anchoring the Detroit Lions' defense with elite tackling metrics. Here is a look at his numbers ahead of the Week 9 Packers game.
The Quiet Force in the Middle of Detroit’s Defense
Jack Campbell does not care about your fantasy football team. He does not care about social media highlights or flashy pre-game outfits either. The Detroit Lions middle linebacker prefers a simpler brand of football. He finds you, he runs through you, and he brings you to the turf.
It is working. As the Lions prepare to host the Green Bay Packers in a high-stakes Week 9 division battle at Ford Field, Campbell has quietly become the undisputed anchor of one of the NFL’s most physical defensive units. He is no longer just a high-draft-pick project with a high motor. In his fourth season, the former Iowa Hawkeye is putting up numbers that demand All-Pro consideration.
Detroit’s coaching staff knew the physical tools were there when they took him 18th overall back in 2023. Now, the mental side of his game has caught up to his massive 6-foot-5 frame. He is directing traffic, making pre-snap adjustments, and erasing running lanes before they even develop.
The Numbers Behind the Hitman
To understand Campbell’s growth, you have to look past basic box score stats. Sure, his 78 total tackles through eight games look great on paper. But the real story lies in his efficiency and efficiency metrics paint a picture of total dominance.
According to league tracking data, Campbell’s missed tackle rate has plummeted to a career-low 4.2% this season. For context, he was hovering around 9.4% during his sophomore campaign in 2024. That means when Campbell gets his hands on a ball-carrier this year, the play is over. He currently ranks second among all NFL inside linebackers with at least 400 snaps in tackling efficiency.

Then there is the concept of “defensive stops” — tackles that result in an offensive failure based on down and distance. Campbell is registering a stop on 12.5% of his run-defense snaps. That puts him in elite territory alongside guys like Fred Warner and Roquan Smith. He is not just scraping by and making tackles five yards downfield. He is meeting running backs in the hole and stopping them dead in their tracks.
Solving the Coverage Conundrum
For years, critics wondered if a linebacker of Campbell’s size could survive in modern pass coverage. Early in his career, offensive coordinators targeted him with speedy running backs and athletic tight ends. He looked stiff at times. He struggled to turn his hips in space.
Not anymore. Defensive coordinator Aaron Glenn has adjusted how the Lions utilize Campbell in zone coverage, keeping him in positions where he can use his length to clog passing lanes. The results have been striking:
- Opposing quarterbacks have a meager 84.2 passer rating when targeting Campbell in zone coverage this season.
- He has allowed just 6.1 yards per completion, a career-best mark.
- He has logged four pass breakups, already matching his previous single-season high.
“He’s just seeing the game faster,” Glenn said during his weekly press conference. “As a young linebacker, your eyes can play tricks on you. You’re looking at the guards, you’re looking at the backfield, you’re trying to see too much. Right now, Jack is trusting his keys. He’s playing fast because he’s playing smart.”
The Week 9 Challenge: Green Bay’s Horizontal Attack
All of those improved metrics will be put to the test this Sunday. The Green Bay Packers bring a highly creative offensive scheme to Detroit. Matt LaFleur loves to stretch defenses horizontally with jet sweeps, run-pass options, and screen passes designed to isolate inside linebackers in open space.

Packers quarterback Jordan Love is playing at a high level, and his ability to hold linebackers with his eyes before throwing behind them is a major threat. Campbell cannot afford to bite on play-action fakes. He has to stay disciplined in his drops while still maintaining enough lateral speed to defend the perimeter run.
“They want to make you run sideline to sideline,” Campbell told reporters at his locker on Wednesday. “They try to tire you out, make you think, and then hit you up the middle. We have to be disciplined. It’s about eleven guys doing their job, not trying to do too much. Just play physical, downhill football.”
Why Campbell’s Rise Changes Detroit’s Ceiling
In previous seasons, the Lions’ defense was often viewed as the weak link of a championship-caliber team. The offense, led by a potent passing game and a dominant offensive line, had to score 30 points a game just to keep Detroit in the win column. That dynamic has flipped in 2026.
With Campbell calling the plays from his middle linebacker spot, the Lions are giving up just 17.4 points per game. They are forcing teams into third-and-long situations and letting their pass rushers hunt. It all starts with stopping the run on early downs, which is Campbell’s specialty.
Lions head coach Dan Campbell, who shares a last name but no relation, smiled when asked about his linebacker’s progression. “He’s a machine,” the head coach said. “He doesn’t say a whole lot. He just works. He’s the first one in the building, last one out. When you see your green-dot linebacker working like that, everyone else has to follow suit. He’s the heartbeat of that group right now.”
Whether the Lions can secure a division crown may well depend on how their defense holds up during this brutal mid-season stretch. If Jack Campbell keeps tackling the way he has through the first two months of the season, Detroit’s defense won’t just hold up — it might just lead them all the way to a championship.
