We need help up front, period.
DT or DE then big linebacker if we move to a 3-4. Then possibly a FS to get Roy back closer to the line.
The CB will take care of themselves with pressure on the line.
Then we need to strengthen the running game - a viable backup for Julius Jones. I possibly see the Cowboys investing in the offensive line because protection for the QB and running lanes start up front.
Wide receiver is way down the list and I'd be surprised to see the Cowboys pick one before the first three rounds.
DTs tend to go off the board fairly quickly. Wilfolk was an aberration last year because the draft was just that deep. The fact that three quality running backs are coming out (Benson, Cadillac and Ronnie Brown) may push some DT talent down to our position.
Right now, I can't really say who we should pick.
Derrick Williams would be a good fit for a 3-4 pass rushing linebacker, but he likely won't be available. Same for Ahmad Brooks if he declares.
I don't know much about Wright and Hawthorne, but I assume the Cowboys could go there. I wouldn't be surprised to see them invest on the defensive line with both first round picks, though I think they'll try to trade down with the second first round pick.
If we get a DT, DE and FS and maybe RB from this draft, I'd be happy. I'm just not that jazzed by the receivers, unless Oklahoma's Bailey is available in the fourth.
