It sure seems like the Rams place a high premium on STs. They talk about them all the time, include "Bones" more pro-actively, and draft with STs in mind and give Bones more leeway to pick his guys than many other teams.
I admit it just might be perception. But the Rams don't have the best STs in the business by accident. STs players aren't the leftovers; they're targeted for that purpose.
And in a league with so much parity, STs can made a critical difference. So imo, it's the right thing to do.
