Perception is not reality when it comes to the Cowboys running game. People have come to identify the Cowboys ground attack with the sumo-sized lines from the '90s. The impression is that Dallas ran a man blocking attack, and each lineman mauled the defender in front of him. They're supposed to be different from the zone blocking attacks associated with the Broncos, the Redskins, Texans and any team with ties to Mike Shanahan.
