they could all have roles

It makes sense that they move Matthews around. But he is also not going to play 60+ snaps per game. So regardless I think Ebukam and Okoronkwo could each carve out situational roles or just be guys that give Matthews a breather. Rams could easily have 6 LBs seeing regular snaps during the season. And of course they will also go to 2-LB sets where Christian and/or Rapp get on the field. A lot of versatility and depth on this defense.
