Iowa's Jack Campbell Named Lions' Next Defensive Leader
Former Iowa Hawkeye standout Jack Campbell is stepping into the biggest role of his NFL career. The Detroit Lions are handing the reins of their defense to Campbell after the departure of veteran captain Alex Anzalone, signaling full confidence in the 2023 first-round pick with a massive contract extension through the 2030 season.
How Campbell Earned the Lions' Trust
Campbell didn't just walk into this leadership role. He earned it the old-fashioned way, through steady improvement and undeniable production on the field. After a rookie season where he had to fight for his starting spot, Campbell became the anchor Detroit needed.
His hard work culminated in a dominant 2025 campaign. Campbell set career-high statistical numbers across the board and earned First Team All-Pro honors. The Lions rewarded that elite performance with a hefty contract extension this offseason, making it clear he is the centerpiece of their defense moving forward.
What Campbell Brings to the Field
The Iowa product has the ideal frame for an NFL middle linebacker. His height allows him to disrupt passing lanes over the middle while shutting down the run game. Campbell was especially dominant against the run in 2025, tallying nine tackles for loss.
He also mastered the art of forcing turnovers, a hallmark of Detroit's defense under head coach Dan Campbell. The linebacker forced three fumbles and recovered two last season. Takeaways are a massive part of the Lions' defensive identity, and Campbell fits that system perfectly.
The numbers back up his dominance. Campbell recorded the lowest missed tackle rate of his career at 7.1 percent and posted an elite 93.0 run defense grade from Pro Football Focus.
Where Campbell Can Still Improve
While Campbell has proven himself against the run, pass coverage remains an area for growth. He has yet to hold opponents below a 100 passer rating on passes thrown his direction in a single season. Becoming a more complete threat in coverage is the natural next step for a player who has already shown he can elevate his game year after year.
What Happens if Campbell Goes Down?
If Campbell were to suffer an injury, it would strike a massive blow to Detroit's defensive depth. As the middle linebacker, he is the engine that makes the entire operation run.
The Lions have Derrick Barnes and Malcolm Rodriguez returning, but both have traditionally played alongside him rather than in his place. Defensive coordinator Kelvin Sheppard has hinted at schematic changes for 2026, which could shake up how the team uses its personnel.
Detroit also added veteran Damone Clark and rookie Jimmy Rolder. Clark lacks significant experience at middle linebacker, meaning he could shift to an outside spot while moving Barnes or Rodriguez inside if needed. Rolder, a promising young player, could be the most likely candidate to step into the middle linebacker role should Campbell miss time, with Clark competing for outside snaps alongside Trevor Nowaske.
Why Campbell Ranks No. 6 for the Lions
Campbell has firmly established himself among Detroit's core players. The contract extension proves the organization's commitment, and his All-Pro talent speaks for itself. Now, he must fill the leadership void left by Anzalone's departure to the Tampa Bay Buccaneers in free agency.
Throughout his career, Campbell has been the model of consistency. His businesslike approach to his craft suggests his best football could still be ahead of him. In 2026, Campbell has the chance to prove his value both as the engine of the Lions defense and as a potential team captain heading into his fourth NFL season.
Why is Jack Campbell So Important to the Lions in 2026?
Campbell is expected to anchor the Detroit defense and fill the leadership void left by Alex Anzalone's departure. His All-Pro level play and new contract extension make him the centerpiece of the team's defensive scheme.
How Did Jack Campbell Perform in the 2025 Season?
Campbell earned First Team All-Pro honors in 2025 after setting career highs in multiple statistical categories. He recorded nine tackles for loss, forced three fumbles, and recovered two while posting an elite 93.0 run defense grade from Pro Football Focus.
