The NFC South can be won this Sunday.
There’s a scenario in which the New Orleans Saints can clinch the division title this Sunday. It’s pretty simple. If the Saints win in Tennessee and the Falcons lose at Carolina, New Orleans wins the NFC South title.
Even if Atlanta wins, there still are some scenarios in which the Saints can at least clinch a wild-card spot this Sunday. If they win and either Detroit or Chicago loses, the Saints are in the playoffs.
By the way, the Falcons (7-5) remain very much in the playoff picture. But there is no scenario in which the Falcons can clinch a playoff berth this weekend.
