Seattle Seahawks could sign defensive tackle Levi Onwuzurike
Onwuzurike missed 2022 due to a back injury, so yeah, that's a bit of a huge concern. But he has been healthy in training camp and the preseason. As a rookie in 2021, Onwuzurike flashed quite a lot of athletic ability in his 396 snaps. He didn't start a game but he still had a handful of pressures and graded decently in pass rush, per Pro Football Focus (subscription required).
Onwuzurike is also capable of playing nose guard which he could either backup Jarran Reed or displace him if Reed needs to scoot over to defensive end. The Seahawks' defensive line is still a massive question mark. Is Dre'Mont Jones truly a transformative player? Can Reed really play nose guard? Is Mario Edwards the kind of end who should get the majority of snaps?
Myles Adams is a decent backup, Cam Young and Mike Morris are rookies who haven't shown they can do anything yet. At least Onwuzurike can play all three spots of the defensive line. But besides his injury concerns from 2022, he does seem to have been outplayed in Lions camp in 2023. Again, and like Kinlaw, maybe he just needs a change of scenery.
Onwuzurike probably hasn't shown all that he's capable, either. He's only played one season and should be better now that he had that experience. And there'd be no pressure on him to start but just rotate in.
