Don't mean to be a downer but Moss and Bonner barely played any CB, while Deluca, Davis, Denbow, Breeze, Leavitt and Apke were all WSTDs (I'm not even familiar with Denbow and I follow the NFL closely), with no regular playing time or anything close to it at safety. Similarly, Laird and Nall had very few touches at RB and are likely finished in the NFL having had no genuine opportunities (Nall already is). So when you're talking about "replacing" these guys, unfortunately they're pretty much non-entities at those verboten positions to the point that there's nothing to replace. The emergence of Blankenship is the only bright spot in recent years at either safety or cornerback.
Hopefully Moss will get more playing time in '24 and may become a starter at some point, and it's exciting to see what DeJean may develop into. But Burkhead was the only other White RB in the last decade besides McCaffrey to see a fair amount of playing time unless you want to count the last gasps of Peyton Hillis in '13 and '14, and the NFL's track record with regard to White RBs over the past 40+ years gives little hope that 3 to 5 White RBs are going to be drafted this year or otherwise get playing time. As always I hope I'm wrong.
