What was the Saints signature win in 2017/18?

The Falcons on Christmas eve.

That game accurately sums up 2017 in a nutshell. The announcers late in the 2nd quarter make a comment of how the Saints defense is dominating despite the low scoring. Our offense struggled on 3rd down all year and in this game, the defense did what they were doing best most of the season by giving the offense second chances to get it right. We had to grind this game out with Smashmouth offense like we had been doing all year as our strength.

13-0 at half time felt like 24-0 and despite only winning 23-13 that game felt like a 40 burger beat down without being one.
