Just saying that anything can happen. Any one of those teams can do it. Thats why they play the game.
I can see the Saints Giants and Bears getting a W. Not so much the Cowboys, Falcons, Lions.
Saints don't have a good enough defense. They will get in a shootout with the Pack and lose.
Bears lost Cutler for the regular season, and the Bears are a wildcard team so they might slip out of the playoffs.
Cowboys have some elite pass rushers that can get to Rodgers, and Romo can air it out to keep up with Rodgers if necessary. Same goes for the Giants pass rushers and Eli.
