For the Dallas Cowboys to truly have a successful season in 2021, they will need their offensive line to return to their former glory. Of course there are other elements that need to come together. Dak Prescott needs to play the majority of the season without injury. The defense absolutely has to be better than last year, and not by just a little, but by a good measure. The coaching staff needs to be better. It’s a long list of things.
But without an offensive line that can power their juggernaut offense, the Cowboys will wither on the vine.
