Just like Jeff Fisher, the New Orleans Saints had enough of 7-9. The Saints were the exact same team the previous three seasons, a team with a great offense and chain link defense that existed solely as a vehicle for Drew Brees to drive around in. This season that has changed. The Saints went 11-5 and won the NFC South.
The defense is what flipped. The previous three seasons the Saints ranked 31st, 32nd, and 31st in defensive DVOA while ranking 7th, 7th, and 6th in offensive DVOA. This season the Saints have an offense DVOA of 23.
