That has to be part of the discussion: who is ready to step in if Fowler, Littleton, or JJ walk?
Howard would step in if Littleton leaves.
Christian started in JJ's spot so I guess either he or Rapp would start at safety if JJ walked.
And then you'd have Obo, Patrick and/or Ebukan at OLB if Fowler leaves.
The one that scares me the most is OLB. What makes it even scarier is Matthews most likely will retire after the 2020 season: if they let Fowler walk then the Rams would have to replace one OLB in 2020 and the other in 2021. I think they have to keep Fowler just to avoid that scenario.
