NFC South schedule: Weeks 1-3
If the Atlanta Falcons can win in week one then the Saints should be their biggest rival for the first three weeks.
The Saints play a Titans team that does not look good on paper and then two teams with unproven quarterbacks. For the Panthers, they obviously have two divisional games to open up and then a Seahawks team that should be able to slice their pass defense to pieces
As for the Buccaneers, I would be shocked if they win more than one game in the first three weeks.
