I suspect the Rams think they have most of the talent they need for the D.
They WILL keep D. Williams or get a 1st rounder for him (maybe a 2nd).
They do have plenty of depth at Safety.
They no doubt will find themselves a vet edge rusher looking for a ring.
And they're good to go with depth on the D line.
Even if they don't upgrade at ILB, they're getting a guy back that they penciled in as a starter last year but got injured.
On O, we don't need to beat this dead horse again. Center and deep threat.
On STs, we need a returner.
You can bet that the Rams have made their priority list and have plans A through D to fulfill it.
The results won't be known for quite some time.
