The Detroit Lions' defense is evolving in the 2024 season under the guidance of defensive coordinator Aaron Glenn. While they've shown improvement, they still occasionally allow key plays.

Despite losing standout Aidan Hutchinson to a severe leg injury, the defensive line remains strong with Alim McNeill and new addition DJ Reader. The linebackers have depth but need consistency, while the secondary has excelled, particularly with safeties Brian Branch and Kerby Joseph, both of whom are on track for Pro Bowl selections.
