Bang for buck, signing premium level RBs and LBs on the open market is a lot cheaper than EDGE, CB,and Tackle. Given we don't have picks in round 2 or round 3, you'd hope we could sign Williams, Pickesns and some depth at LB and RB given the relative free-market acquisition cost.
Then, come draft time prey a couple of those premium positions picks are available when we're on deck, but the rest of the draft has to be BPA and we need depth at CB (assuming Diggs is gone), LB, Edge, Safety, and RB2. Add T to the list if turn-Steele does't step it up down the stretch.
P.O.N. assuming we sign Pickens:
CB
LB
EDGE
S
RB
T (If Steele gets cut)
