What was the Saints signature win in 2017/18?

Signature in terms of coming back from near-certain defeat was the Washington game. The Skins choked that game away like we used to back during the bad ol' days.

Signature in terms of importance in the standings were both wins over Carolina during the regular season. The first one, on the road, was do-or-die in terms of saving the season after the bad start. The second one solidified the Saints as the division's best.
