Mailbag: Did Detroit Lions’ draft hint at defensive scheme changes?

The Detroit Lions defense needed some serious changes this offseason after the team’s efficiency dropped from the seventh-best scoring defense to 22nd in 2025. Detroit promised to look at everything, and while a complete overhaul of the scheme they’ve been using since 2021 was always unlikely, coaches have promised that they will tweak the system to fit the talent of their players.

Last weekend, the Lions drafted defensive players with five of their seven selections, showcasing that they need there was a talent deficiency on that side of the ball. But can their specific picks tell us anything about the strategic, schematic, or philosophical tweaks they are making to the team?

On one hand, all you have to do is look at the pure numbers of players at each position to suggest there may be some personnel changes in 2026. The Lions played more based defense (three linebacker sets) than anyone in 2025, but if you look at their depth chart right now (including the Lions’ two signings on Wednedsay), Detroit only has eight linebackers (including reported UDFA signing Erick Hunter) compared to 16 defensive backs. Detroit has several members of the secondary who can play in the slot, so is this a sign they plan on playing more nickel in 2026?

Additionally, the players they added to the defensive line seem to bring more pass rush juice than run stuffing. And Detroit has yet to really add a nose tackle to replace the likes DJ Reader or Roy Lopez. Has the team quietly admitted they’ve relied too much on stopping the run and need to tilt the scales a little more toward rushing the passer?

Or we could take things even further. With no true nose tackle, but several movable parts on the interior defensive line, could we see the Lions move to a 3-4 base defense? Given how much we’ve seen Aidan Hutchinson, DJ Wonnum, and rookie Derrick Moore play as a stand-up defensive end, Detroit would certainly have the personnel to make a change like that, especially considering it would only require two true off-ball linebackers. But is that too drastic of a change?
