I think any RB added will be strictly PS. It could be a vet or a young player with limited experience. Most vested vets are not going to want to sign a PS contract. I think offensively we will see a lot of 2018 concepts. It's the defense that I'm most curious about. I know Morris will play primarily zone because that is what he's most comfortable with and he's going to try to build upon Staley's zone concepts. If there are going to change that is where it will be, i.e. in the implementation of the scheme.
The roster is pretty much the way I pictured it would be. The only positions they are overly deep at is NT and safety. Fuller and Rapp are basically SS types with Hughes and Reed being more of what you expect at FS in terms of build and speed. Burgess is a hybrid DB who can play CB as well as FS. Burgess makes the secondary 5 deep at safety and CB. I think he will play both Rapp and Burgess as SS/coverage LBs.
I like the makeup of this roster. It's loaded with talent. Now it's a matter of it being used properly. In that regard, I hope Morris will be more aggressive with his secondary. They were very passive in pre-season stressing reacting to the pass instead of coverage like Staley emphasized. I think that style in the preseason had a lot to do with the poor speed of the DBs he was playing with. Harris was basically toast if he had to play man coverage.
The only criticism I might have with the makeup of the secondary is Reed instead of Deayon. Reed is what you expect if you are playing strictly a zone scheme, whereas Deayon gives the ability to play both zone or man. I think Morris and McVay feel they have what Deayon brings in Hughes and to a certain extent I agree. As long as Reed can stay ahead of the play and play downhill he will be fine. That's why I put Reed as the #5 safety.
