I see these positions as needing starters, not depth (QB, ILB, OLB, S), and these as needing depth but have starters (RB, WR, DE, DT, TE, OT). CB is a tough one, as Rhoades and Munnerlyn are the set starters, but nickel is almost a starter. But I would like to see what Zimmer (who has got good things out of almost all his corners), can do with guys like Robinson and Cox and Prater (who IMO looked really good in limited time).
That's pretty much why I want to see a LB or a QB as our first round pick. We just have 0 top level talent at those positions.
