I think sometimes fans and the media think there is 1 way to go to build a winner...no, don't take a QB high, take an OL high etc.
Bottom line:
You need a top GM to draft players that can make playes, no matter if it is a LB, DT, DE, SS, QB, WR or RB.
AND those players must fit what you are trying to do as a team...Cover 2...3-4, West Coast offense, pistol...whatever the case may be.
