Diggs, the right early pick rookie, Kincaid, Shakir, Knox, Cook. If you can't win with that you don't have a weapons problem IMO.
Like I say if the draft falls where there is a receiver sticking out for them after they have taken one then by all means. But they don't need two. One receiver who plays outside and has game breaking speed is a need on this team. Another receiver isn't necessarily a stupid pick but it isn't a need.
Their needs will be WR, DL and S.
