Carolina Panthers
FPI chance to win Super Bowl: 0.5%
Concerning weakness: Third-down defense
The Panthers' defense has a very hard time getting off the field. Carolina ranks 15th on first down by DVOA and 13th on second down. Yet they rank 31st on third down, ahead of only the Cowboys. If you prefer more conventional stats, they rank 31st in conversion rate allowed on third downs; opponents move the sticks 46.7% of the time against the Panthers on third down and 63.6% of the time on fourth down.
The Panthers managed to force two turnovers on third down against the Rams in their Week 13 upset, but this is not a trend that has gotten any better in recent weeks. And the top offenses on third down this season include the 49ers, Packers, Eagles and Rams.
