The New Orleans Saints are one of the most vividly-illustrative cases of what happens when you combine a highly-functional offense with one of the worst defenses of all-time.

The Saints finished second in overall offensive efficiency while finishing dead-last (by an enormous margin) in total defensive efficiency, according to our schedule-adjusted metrics. The fact that Drew Brees finds his way onto this list largely explains how the Saints managed seven wins with such a putrid defense.

Brees completed 68.3 percent of his 3rd-down pass attempts, second behind only Josh McCown. While he threw just 3 touchdowns to 4 interceptions, he finished with the third-best Success Rate (48.85%).
