Tobias made a good point; the running game of Atlanta isn't what it was last year, and they know a shoot-out will end up with high point totals for the Saints.
The other factor is that the Falcons' secondary has been performing very similarly to the NY Jets. They're susceptible to big plays and they have undersized corners. Brees loves throwing to his tall boys even when covered, and the Saints usually win those battles.

It's a good matchup for the Saints, but they need to maintain momentum. The Falcons are talented and they've only lost 2 games to quality opponents.
