The New Orleans Saints have won the NFC South over the long haul.
The division came into existence in 2002. I just received the NFL’s official Record & Fact Book, which contains records for every team starting in 2002 and running through the 2011 season.
The Saints went an NFC South-best 90-70 (.563) in that span. Only Philadelphia (.622) and Green Bay (.619) had better records in that time frame among NFC teams. The Atlanta Falcons weren’t far behind. They’ve gone 87-72 (.542). After the Saints and Falcons, there is a pretty big drop off in the NFC South with the other two teams coming in below .500.
Carolina is 79-81 (.494) and Tampa Bay is 74-86 (,463).
When it comes to home records from 2002 through 2011, Atlanta is the winner. The Falcons are 50-30 (.625) in the Georgia Dome. Only Green Bay (.688) and Seattle (.638) have better home records. New Orleans is 45-35 (.563), Carolina is 42-38 (.525) and Tampa Bay is 42-38 (.525).
