So if Green Bay had the power to draft Luck a few years ago they should have done it? BPA does require they actually see the field. I am not advocating for drafting purely based on need because teams that do that lose. I am advocating against blindly following a board and ignoring what players you actually have. Going from Weddler to Hooker is a small upgrade at best, but grabbing Reddick or Barnett or even trading back to grab great 2nd round picks is a MUCH bigger upgrade to the roster overall.
The goal of the draft is to make your roster stronger and I would rather go from a 3 to an 8 at a major impact position then an 9 to a 9.5.
