Only 3 of these score out as starter level. The other 4 score out as replaceable. Most of them have a very limited sample of games/ plays to base the grades on so wouldn't draw too much of a conclusion.
Plus rookie cornerbacks
Jerry Jacobs (64.8) and
AJ Parker (50.2). Hopefully Jerry makes a full recovery bc he was outstanding for a rookie CB - IIRC Slay was mid-50s his rookie year. Parker always seemed like a depth guy, nothing more, wouldn't have gotten the snaps he did if we didn't go through DBs like socks this year. But Jacobs could be a starter in two years (I'm presuming Y1 he won't be all the way back.)
Thinking about Lions DBs....
Iffy has the size to develop into a press corner. We kind of knew going in he was going to be a project. Who knows what will become of Okudah. Amani Oruwariye is very similar to Trevon Diggs - just OK in coverage but great ball skills. He should be fully rehabbed by TC next year but he was awful in preseason and to start the year. But overall CB seems like it's covered for 2022, though as we know you can never have too much depth there.
Will Harris, incredibly, still has another year on his contract. He has been a putrid S for three years (though he actually played well as emergency CB v the Cards.) Walker is a FA, played well, they should bring him back. Not sure about Dean Marlowe's status but he was decent this year. Maybe move Okudah to the back line bc he doesn't seem like a good fit outside.
I don't mind if they draft a S in the middle/late rounds but i'd prefer they address the position group through mid/low level FA signings. Much more pressing needs at WR, LB and EDGE.

Alim looks like he'll be the NT for as long as he's healthy. I hope
Levi develops, it was a new position for him and he was hurt in camp, but def a disappointing year.
Derrick flashed at times - had a good game in the abysmal loss to the Bengals, and saw more significant time Week 13 onward. Hoping he continues to grow but the early returns are kind of meh.
The three offensive rookies looked better but as you alluded to the sample size for JJ is too small to render a verdict. He's not a thumper, not shifty enough to be a satellite back, hasn't shown much in pass pro. If everyone goes down he can fill in but IDK that he's any better than Ilgwebuike, Netflix or any random RB off the street.
ARSB and Sewell are foundational pieces. Penei might have a Jackie Slater career for Detroit if he stays healthy.
Solid overall, but tbh I hope we can get more than 2.5 starters from the 2022 draft.
