I'll probably get seriously flamed for this but...

Sure, the Falcons played as bad as the Saints played well. Both factor into the outcome. Still, the Falcons just didn't show any real ability to get the ball in the endzone on the chances they had so had a couple of drives stayed alive for them, I can't conclude that the outcome of the game would have been drastically different. Possibly, sure, but it would have meant they capitalized on those drives that ended on drops differently from how they did when they actually had themselves in scoring position.
