Um, you forgot one thing. Saints SB wins: 1 Falcons SB wins: 0
Oh and since Sean Payton came to town... prior to the "big win" earlier this year (that the Saints gave the Falcons): Saints 8 Falcons 1
So yes it's like little brother (Falcons) getting all excited because he beat big brother (Sean Payton's Saints).
And if you look at the decade prior to this year (2000-2009), the Saints have the edge 13-7 in head to head competition, as we were 6-6 prior to Payton showing up.
