I think you're all selling New Orleans short. They're 4-5. Despite their record, they are still a good home team, and are likely to finish with 6 or 7 home wins. Their remaining home games are Cincinnati, Baltimore, Carolina, and Atlanta. They will probably win 3 or all 4 of those, putting them at 6 or 7 home wins.
Their struggles are on the road. Their remaining road games are at Pittsburgh, at Chicago, and at Tampa Bay. Tampa Bay is an automatic win. The Bears suck and the Saints could very easily beat them in Chicago. They will probably lose to Pittsburgh.
They will most likely win 9 or 10 games. We could still have to go there as a wild card, but it wouldn't be the poetic justice of us as the defending SB champs playing on the road at a 7-9 team.
