The Green Bay Packers’ worst rushing defense of the last decade was almost certainly 2013. Dating back to 2010, it was the only year prior to 2022 in which the team allowed a positive EPA/play to opposing rushers. It was also the only year of the last decade, prior to 2022, where they scored a positive rush defense DVOA.
(An important reminder: While on offense, positive EPA/DVOA numbers are good, the opposite is true for defenses. Negative numbers for EPA/Play and DVOA are good for the defense in question, and positive numbers are bad.
