The Carolina Panthers have spent most of the 2015 season as the big dogs of the National Football League, thanks in large part to a defense that ranks sixth in the league in both yards and points allowed.
However, despite the presence of All-Pro cornerback Josh Norman, the Carolina secondary is the Achilles' heel of its defense, and that secondary faces its toughest test of the season Sunday in the one game standing between the Panthers and a berth in Super Bowl 50.
There hasn't been a better team at attacking defenses through the air this season than the Arizona Cardinals.
