They definately don't need D linemen. They'll be playing a 3-4 next year and they unloaded the overpaid rejects to Denver. O-line definately. But there certainly was nobody close to deserving of that high of a pick. I'm sure they tried to trade the pick down but there weren't too many teams willing to move up unless they maybe needed a RB (which was the strongest top 10 position).
I wouldn't even call Dennis Nortcutt and Andre Davis adequate. Their overall WR production was one of the worst in the league last year in terms of receptions and yardage. Hopefully, with more of a big play threat and Winslow coming back from injury, they can stratch the defense a little bit.
