The performance of National Football League defensive units in 2011 was assessed and categorized based on various statistical metrics. These evaluations provided a quantifiable measure of each team’s ability to prevent opponents from scoring and gaining yardage. Teams were ranked according to key defensive statistics such as points allowed per game, total yards allowed, passing yards allowed, and rushing yards allowed, culminating in a comprehensive league-wide comparison.
These comparative assessments are valuable for understanding team strengths and weaknesses, informing strategic decisions for both teams and fans. Historically, examining these ratings offers insight into the evolving strategies and player personnel changes within the league. They also provide context for understanding the success or failure of teams based on their ability to limit opposing offenses during that particular season.
