Cowboys defense slammed for miscommunication after Giants loss

In the 2026 NFL season opener on September 13, the Dallas Cowboys lost 28-20 to the New York Giants in Arlington, Texas. The Cowboys' defense, which was a major weakness in 2025, struggled again, allowing 394 yards and four touchdowns. The Giants converted nine of eleven third downs, keeping the ball for nearly 37 minutes. Defensive tackle Quinnen Williams acknowledged the team's mental errors and called for critical self-assessment. Former All-Pro Devin McCourty criticized the defense for miscommunication and missed tackles, saying they allowed two touchdowns where receivers were left uncovered. The Cowboys must improve before facing the Washington Commanders in Week 2.
