Key defenders like Micah Parsons and DeMarcus Lawrence have missed substantial time due to injuries, which has severely impacted the team's defensive strategy and execution.

As a result of these challenges, the Cowboys currently rank lower in key defensive statistics than they did during any of Quinn's first three seasons, allowing an average of 365.7 yards and 29.3 points per game.

With the Cowboys set to face Quinn's Washington Commanders on November 24, 2024, their defensive performance has notably declined compared to previous seasons.

Players have voiced criticism regarding the defense's performance, emphasizing the need for self-accountability and a stronger will to win.

Amid these struggles, players have acknowledged the challenge of filling in for injured teammates, prompting Zimmer to adjust his defensive schemes on the fly.

Despite the difficulties, there is a sense of optimism as key players like Parsons and DaRon Bland may return for the upcoming game against the Commanders.

Interestingly, despite some overall struggles, Zimmer's defense has shown improvement in passing yards allowed, averaging 214.7 yards per game this season compared to 251.9 in Quinn's first season.

The Dallas Cowboys are undergoing a significant transition as they shift from Dan Quinn to Mike Zimmer as their defensive coordinator.

Returning after a two-year hiatus from coaching, Zimmer has faced the challenge of adapting his game plans to accommodate changing personnel and numerous injuries.

Injuries have taken a toll on the Cowboys' defense this season, with a staggering 40 games lost among defensive players contributing to their underperformance.
