If we only wanted to completely fix one group this draft and another next, we could really come away from this draft with either a total OL upgrade or a total DL/DE upgrade, or even a total DB upgrade, although I would put the DB upgrade as not needing complete total upgrade.
If we don't trade back and go with Carter or Anderson, we can easily pick up the other position at the top of R2.
Trading back would probably have us starting off with the OL or CB. A top CB would probably do it for this draft. Or if we went OG, OC, even OT with our first few picks could secure us a dominant OL at the rookie salary schedule and keep Murray secure for the length of Murray's contract.
I highly suspect however that will spread out our picks over all 3 of these groups, DL, OL, and DB. I would be happy with any of those directions. We just don't need (and are sick and tired of) wasting high picks on positions of least need like TE, little WRs and RBs, LBs, .....
