To keep it short, the Carolina Panthers had a great season in 2013. They improved in many aspects, but their most prized performance came from their defense. Their offense was good, too, but it was truly their defense that carried them as deep into the playoffs as they went.
That all being said, there are still some serious improvements to be made by the Panthers.
Improving their passing attack with Cam Newton is one of their more pressing issues, and bandaging that will begin once free agency opens.
They also need to improve the single crack in their defensive armor, the secondary. They allowed opposing quarterbacks to be entirely too efficient against them, and that will need to be resolved if they are to take another step forward in 2014.
Statistically, there isn't a whole lot to be mad about with the Panthers—but they do have moves that they must make.
