Offensively they needed to find a way to move the ball on the ground. Too many times they got in situations where they had to throw and Seattle was able to make plays with pressure and defending routes. They had early opportunities for big plays. Unlike the Giants game, they did not convert.
The defense had some early success against the rookie quarterback, Russell Wilson. But the inability to control Marshawn Lynch was their big downfall. The Seahawks offensive line was able to control the line of scrimmage in the second half denying the Cowboys offense valuable possessions.
Ten Seattle points came from special teams turnovers. You cannot spot these points to a team that struggled to score offensive touchdowns. Joe Decimilus spends a great deal of practice working on all phases of special teams. In this game breakdowns on the punt and kickoff return cost Dallas dearly.
