"There's a few changes," Campbell said of the defense under Sheppard. "There's some things I'm excited about that the back end is excited about and the guys upfront are excited about. It's going to be good, I think, but you have to learn with it.
"Little nuances within the call that's a little bit different than what coach (Aaron) Glenn did. I'm just excited to see what happens. We have the right guys in the room ... so I'm excited."
It's certainly a lot healthier of a defensive room for the Lions right now than how they finished 2024 with 18 defenders on injured reserve, including key players like Hutchinson, Alim McNeill, Derrick Barnes, Marcus Davenport and many others. Campbell likes the pieces in place and once Sheppard's scheme is fully implemented, he thinks there's no reason Detroit can't have one of the more productive defenses in the NFL in 2025.
