Yeah I agree that CB, RB, and OL would be bad picks. Just trying to think of the priorities of the team, Ryan puts corners at a premium, running the ball is key which makes having backs for carries (I'd prefer a mid-rounder) and the big guys to open holes important. Luckily Slauson played alright, hopefully Ducasse progresses a lot so they're basically set on the OL for awhile. The recent report that they're going to let Cro walk makes a corner more likely too IMO, and could be some of Kiper's surprise.
The young DL's, Dixon and Tevaseu included, are probably factors. I'd guess they like them a good amount.
Purely speculating on the other ones, I think they try to bring back both but are ultimately unsuccessful, Leonhard I think will be fine but I wonder if either of Pool and Smith are brought back, and I think Woody's a cap casualty but Hunter's brought back on the cheap to compete with Vlad.
I would definitely not be surprised if the first rounder was not in the front seven, but would be disappointed. An infusion of youth and talent is needed there IMO.
