Dak is changing the plays at the line of scrimmage far more and made great decisions in the opener while uncharacteristically failing to execute some open passes. In Week 2's loss at Denver, Prescott must have been shocked to see his teammates so physically manhandled. It just didn't happen last season. Against the Broncos, tackles Tyron Smith and Collins were often beat on the same play and the team lacked any vertical presence. Dez Bryant is missing explosiveness and the Cowboys' offense has struggled to keep the ball.
