I was thinking of a somewhat similar plan, from a personnel point of view.
1 - OL - Pugh, Jones, and Fluker should remain starters at LG, C, and RG respectively. We're left with a dire need for starting caliber RT and LT. This is one I'd address via free agency rather than the draft. Behind them, can draft mid-rounds for depth and future development.
2 - LB situation - Casillas, Kennard, Robinson, and Sheppard are all free agents. They were also nothing special anyway. I'd like them all walk, unless we can get Kennard on the cheap to remain at SAM. In any case, we need to bring in two starting caliber outside LBs, particularly a WILL LB.
3 - QB - Draft either Darnold or Rosen,with the top 3-4 pick. Eli should have one or two good years left in him, and they can develop behind him.
4 - Next in line for priorities is the secondary. Draft heavy in the mid-rounds at CB and S.
5 - Remaining priorities are RB and depth at DL.
