Currently on the roster the Rams have Ebukam, Floyd, Patrick, and Lawler as OLBs (in addition to he who shall not be named).
Among the ILBs I suppose Howard, Polite, and possibly Young have some pop.
AD, of course, will be in the backfield a lot. The addition of Robinson pushes Joseph-Day to DE but it doesn't seem likely that he'll be a factor in the pass rush even from his DE spot.
Probably looking for help in the draft and/or at some point in FA when prices start to drop. Until then that's it ...
