Looking at your draft scenario, I throw out both of your trades as unrealistic, and come up with the following:
23 - William Beatty, OT. Chance to get a 10 year pro-bowl calibre LOT is too good to pass up.
34 - Connor Barwin, OLB. I love Sean Smith, and if we got Gocong I could understand your reasoning, but I don't see it happening, and a pass rushing OLB is a higher priority given the options at S in the 2nd round.
47 - Louis Delmas, S. Perfect hit. Needs to add 10 lbs. Lack of incredible physical upside may allow him to slip this far.
58 - Hakeem Nicks, WR. Don't believe he will fall this far, but would jump all over him if he did. Reminds me of Jerry Rice.
89 - Jarron Gilbert, DE. If we actually got Nicks at 58 and Gilbert at 89 I would be in 7th heaven. It won't happen, but I'll keep dreaming for now. I see more realistically trading this pick with #58 to move up to around #43 if Nicks is still available.
The only really major need that I would like to see addressed in addition to these picks would be an SILB to go along with Mayo and Guyton, but you can't have anything. And you have my preferred SILB candidate, Robert Ayers, going #11.
Throw in an OG at #97 and a DT backup for Vince Wilfork in the 4th round, and we would be pretty well set.
