The Dallas Cowboys' defense has shown little improvement from last season. Despite a new defensive coordinator, 34-year-old Christian Parker, and significant roster changes, the team's performance in their season-opening loss was reminiscent of last year's struggles. The New York Giants had notable success on third down, converting 9 of 10 attempts, and were able to control the ball for extended periods in the second half.

Further details on the game are available from the source. The Cowboys' defense allowed the Giants to have two long touchdown drives in the second half, and the team's secondary struggled to cover receivers. The run defense also had difficulties, although specific details are not provided here.
