Mike Zimmer had his work cut out for him in his first season back as the Dallas Cowboys defensive coordinator. He lost Dorance Armstrong, the defensive lineman with the second-most sacks over the last two seasons, to the Washington Commanders, as well as Dante Fowler, Jr., who had 10 sacks across his two years in Dallas. Also gone are starting DT Jonathan Hankins, rotational DT Neville Gallimore and starting middle linebacker Leighton Vander Esch, who sustained a career-ending injury.

Implementing a new defensive scheme, the team only added Eric Kendricks in free agency before training camp. He got a few defensive line additions late in camp, but getting his new ideas to his new players would take time. Tom compound things, the injuries hit. He lost edge rusher Sam Williams for the season and All-Pro corner DaRon Bland for 11 games due to injury. Bad defensive performances against the New Orleans Saints and Baltimore Ravens were the precursor as in-season injuries began to mount.

Both Micah Parsons and Demarcus Lawrence went out against the Ravens, and Marshawn Kneeland went down the following week against the Pittsburgh Steelers. That left Zimmer without his top-four edge rushers after just five weeks.

The coach is trying to get the team better against the run, which is the biggest issue for the Cowboys in the Dak Prescott era, but he has their pass rush eliminated, his biggest weapon. His defensive back luck wasn’t any better.

The team hasn’t had Bland, Trevon Diggs, and Jourdan Lewis together for a single game all season.

The second cornerback spot has been a rotating door. They lost rookie Caelen Carson to injury, called up Amani Oruwariye and Josh Butler from the practice squad, but lost both to injury as well. Markquese Bell and Juanyeh Thomas, rotational defensive backs, are the latest to suffer major ailments.

With all those disadvantages, the Dallas defense has continued to improve. Starting in Week 8, the defense was good in the first half of nearly every game before wearing down in the second half. The San Francisco 49ers scored six points, and the Atlanta Falcons and Philadelphia Eagles scored 14, but each scored off of Dallas turnovers. So did the Houston Texans, who got to 17 at halftime. The Commanders scored only three points, and the New York Giants got to 10, but DeMarvion Overshown scored a touchdown for the defense against the Giants.

Between Week 2 and Week 6, Dallas allowed 19 points on average in the first half, but since it’s down to nine.

Zimmer has Parsons and Bland back, and it has helped flip from one of the worst turnover ratios, to having five takeaways to one turnover in the last two games. The defense is getting sacks now, too, from 20 in the first 10 games to 10 in the last two.

The Cincinnati Bengals, Dallas’ Week 14 opponent, are averaging 35 points per contest over their last four games. Zimmer is going to get tested by his old team, but if his defense can keep a below-average Cowboys offense in the game, then Zimmer might officially put to rest a lot of sentiments from earlier in the season.
