With injuries mounting in the secondary, the Detroit Lions are adjusting their defensive approach — and that shift starts at linebacker. Led by Jack Campbell, Detroit’s linebacking group is expected to shoulder more responsibility as the team works to stabilize coverage on the back end.
Campbell has quietly become the nerve center of the defense. His growth in play recognition, downhill tackling, and communication has positioned him as the natural focal point for a unit now asked to do more than just stop the run. The Lions are increasingly relying on their linebackers to close passing lanes underneath, disguise coverage looks, and help prevent explosive plays over the middle.
This adjustment isn’t accidental. With fewer proven options available in the secondary, Detroit’s defensive success now hinges on reducing quarterback comfort early in the down. That means tighter zone drops, quicker reactions to play-action, and linebackers who can hold up in space — areas where Campbell has shown consistent improvement.
The approach also reflects Detroit’s identity. Rather than playing passive to protect weaknesses, the Lions are leaning into physicality and structure. If the linebackers can control the middle of the field, it limits how much stress reaches the defensive backs behind them.
As the season pushes deeper into its most demanding stretch, Detroit’s margin for error is slim. But if Jack Campbell continues to rise, the Lions may find that their defense doesn’t need to be perfect — just disciplined, connected, and aggressive where it counts most.
