The Dallas Cowboys struggled defensively in 2020. At times, they were the worst defense in franchise history under now-former defensive coordinator Mike Nolan.
But this unit was able to bounce back in their final four games, winning three of them, and allowing an average of only 20.0 points per contest to opposing offenses during that span.
Despite the improved play, which also included averaging three takeaways per game, the Cowboys defense still finished the season ranked as one of the worst units in the NFL.
