It wasn’t that long ago when the defense of the Dallas Cowboys was a huge liability for this team. From 2010 to 2015, the Cowboys' defense never finished inside the top 15 for the fewest points allowed. Things got better in 2016 but took a turn for the worse when Mike Nolan’s defense allowed a franchise-worst 473 points in 2020. Needless to say, Nolan’s services were no longer required.
The addition of Dan Quinn has this defense singing a whole other tune as the Cowboys have finished in the top seven in points allowed in each of the past two seasons.
