It is incredibly easy, and naive...to look back and say the team has ignored a position.
First, no team ignores any position. Just doesn't happen. From the fans perspective, they don't have the same perspective as the team does, and therefore lacks the understanding of the team.
Second, most drafts do not go as planned. Outside of the top 5 picks, the direction of any and every draft go way off anybody's ability to predict.
Third, the teams knowledge of players already on the team is much more intimate than a fan could possibly be. Fans perspective of any player they don't like or agree with, is incredibly negative. Teams are going to sign a free agent they feel won't beat out the players the team already has on roster.
Free agency has made it more difficult to assemble and keep a talented line together. I know the is the opposite of many thoughts...as a life long football fan, it's painfully obvious.
