The more time has gone by the more I agree with this. Although, i'll be happy with any of the top defensive prospects in round 1 even if it is not Chubb.
I think most would agree that a big part of the current offensive line problems revolve around the scheme/play calling. There is not enough short passing. Also, the QB scrambling (whether Brissett or Luck) does not help the offensive line either. An offense based on quick passes will make even our current line look better.
I certainly will not be mad if the Colts draft Nelson in round 1. I just think the line can be improved in free agency and with coaching. Assuming the Colts end up with a top pick in the draft I would rather use it on a top defensive player.
