Since 2006 when Sean Payton took over as head coach the Saints have sported a 13-3 win/loss mark against Atlanta and Payton-coached teams (2012 not included) have gone 12-2 against the Falcons.
In Atlanta the Saints are 6-2 since 2006 and Payton has sported a 6-1 win/loss record in the ATL.
These games have normally been close, but the Saints have owned the Falcons since 2006 and it didn't matter where they played.
2. Road Record
Saints fans hear it from local and national media types that the team is not a good regular season "road" team. That statement is not based on facts.
The Saints have not done well on the road at playoff time, only one road win against the Philadelphia Eagles following the 2013 regular season, but in fact since 2009 the Saints have gone 24-16.
They are tied with the New England Patriots (24-16) for the best road record in the NFL since 2009 and the Green Bay Packers are third with a mark of 23-17.
The Saints were 3-5 last season on the road, but they are in fact and have been a very good regular season "road" team.
