Carroll would have coached that Dallas team to victory.
He would have run Murray into the ground in the second half and controlled the tempo of that game. It is the second half, when 300+ pound defensive lineman are getting tired, when the running game comes to life. It was mistakes in the Dallas passing game that caused that loss. Bumbled snap in the shotgun, taking sacks instead of throwing the ball away. Not giving the leading rusher in the NFL a chance to dominate.
Dallas went back to 8-8 Dallas philosophy. They didn't stick with what got them there.
