I like your use of the term “thin”, backer.
Better describes our situation at LB and OL, I think.
I believe that S&M will be able to find a JJ or Ebu type gem with a couple of their early picks. They won’t be household names, but they can be solid players that might be contributors this season. Heck, might get starter snaps by midseason. A couple of others will be developmental and possible future contributors.
This roster is pretty loaded at the top so new starters will be few and far between. Just making the 53 will be a hell of an accomplishment, tbh. Nevertheless, I fully expect S&M to find and develop a few gems.
