By just about any statistic that you would care to come up with, the Jacksonville Jaguars finished with the best pass defense in the NFL during the 2017 regular season. Their 169.9 passing yards allowed per game? The best in the league. Their six yards per pass attempt allowed? The best in the league. Their 68.5 quarterback rating? The best in the league. Their touchdown-to-interception ratio? The best in the league.
So then you might be surprised to learn that their defense was actually one of the most highly-exploited when it comes to allowing big plays.
