Gettleman comes from a pro scouting background. He wanted to beef up our dline last year so with our first 2 picks he got us 2 of the best DT's in the draft. I have little doubt that since all of us see our weaknesses as WR, oline, CB that it is apparent to him also. He can't address all 3 of those sufficiently just in the draft. IMO it is much easier to find oline (particularly OG) and secondary help in Free Agency.
Teams DO NOT let players with number 1 WR talent hit the market unless they have serious issues(health, attitude,etc). It's not just about what is more important to a team, WR or oline, but also which one is easier to address in free agency. By all accounts this year's WR crop is much better than last year's and we have all seen receivers from that class come in and make an impact. Go get Cam at least 1 big time WR. If a great OT falls to us of course you have to consider taking him at 1. BPA between WR and OT with our first and get the other with our 2nd pick.
Corner is a need but Rivera has shown he can coach up DB's, I trust him to make up for defensive deficiencies MUCH more than Shula to make up for a weak line and WR's that don't scare anyone.
