The Dallas Cowboys' defense struggled in their season-opening loss to the New York Giants. Despite a new defensive coordinator, 34-year-old Christian Parker, and roster changes, the team's performance was similar to the previous year. The Giants had two lengthy touchdown drives in the second half and successfully ran out the clock on their final possession.

The Cowboys' defense had difficulty stopping the Giants on third down, allowing them to convert 9 of 10 attempts. Receivers were often left unguarded in the secondary, and the run defense was porous at key moments.

Further details on the game and the Cowboys' performance are available from the source. The final score was 28-20 in favor of the New York Giants.
