If the d-line continues to dominate, I think you have to resign Hardy and allow your high first round pick to be used on either RB/secondary/interior d-line.
I've been on this board for many years now, and the most common theme that people have always clamored for is physicality in the trenches. The o-line speaks for itself, but I don't see how this team doesn't bounce back and find major success if the defensive line continues to improve along the same curve the offensive line did.
The formula for a dominant team is there. Yes there are some missing pieces still, but with a solid draft aided by picking highly, we are still very much poised to make a run as long as Romo stays upright. If they can create a dominant defense and running game, Romo will simply have to manage games which should also extend his career.
We will be a young, talented, VENGEFUL team next year. Can't wait.
