The loser of Sunday's game in Green Bay between the New Orleans Saints and Packers was going to face a big hole to dig out of to get to the NFL playoffs. Turns out it was the Saints, who lost, 28-27, to go 0-4 and fall four games behind Atlanta in the NFC South one-quarter of the way through the regular season.
By pulling out the win, Green Bay evened its record at 2-2, one game behind surprising Minnesota in the NFC North.
Atlanta was one of the NFL's three unbeaten teams to emerge unscathed - just barely. The Falcons scored last in a back-and-forth game and edged Cam Newton and the visiting Carolina Panthers, 30-28. Houston joined the Falcons at 4-0 with a routine home win over Tennessee, 38-14. Arizona, also 4-0, needed overtime to defeat visiting Miami, 24-21.
