Falcons only 1 game better than Saints

The Falcons are only 1 game better than the Saints despite having their starting QB available all season so far and pretty much remaining healthy all season team wise. I would be very concerned in Atlanta if I were a fan.
In actuality Atlanta is a1.5 games ahead with the tie breaker. They are 4-1 in the division and the Saints are 2-3 so the Saints can't get ahead of Atlanta in the Division tie breaker.
