Read this article and answer this question Due to the Falcons' loss to the Buccaneers earlier that same day, the Panthers entered this game having already clinched their third straight NFC South title&#8212;becoming the first team in the 2015 season to clinch a playoff berth, as well as the first team to clinch their division that season. Led by Drew Brees and a determined defense, New Orleans fought hard all game, their defense recovering three Panthers turnovers- including the first returned extra point attempt for points in NFL history. In the end, Carolina needed a 4th quarter game-winning touchdown drive from the offense (including a 4th down conversion), and a last-second defensive stand to seal it. With the thrilling win, the Panthers became the 9th team in NFL history to start the season 12-0. They also matched their franchise record for most victories in a season.
How many other teams started 12-0 before the Panthers achieved that same feat?
