You don't get to just pick and choose the players that come available in the order that you deem the most important needs. You can only trade for guys other teams want to trade, sign guys who are FAs, or draft guys on the board.
The only two "starters" you mentioned are Safety and EDGE. Everything else you had above WR was depth, but in the meantime Hollins/Pop/Williams/Chism are combing for like 75% playing time as the 3rd WR in our offense and contributing nothing basically except for one deep shot to Douglas last game. I'd agree that needs at EDGE/Safety trounce that, but lacking a competent 3rd WR is more determinantal to the team than a 3rd TE or backup slot CB. 3rd WR is an actual starting position.
