The Carolina Panthers may have been one-and-done in the playoffs, but they had such a promising season in 2013 that there is much to be hopeful about. They don't have a whole lot of weaknesses on their roster and actually have a lot of strengths, such as their running backs and defensive line.
When it does come to their weaknesses, the Panthers are most troubled in their secondary. They do have some talent back there in Captain Munnerlyn, but an upgrade in the secondary is definitely needed, and they could find their man in free agency. This is, of course, assuming that they re-sign key free agents like Munnerlyn and Jordan Gross.
Even if they are able to bring back Gross, they will still need a solid option for the opposite side of their offensive line at the right tackle position. They may look to a veteran guy like Eric Winston to fill that spot, which, considering what he brings to the table as a proven, talented veteran lineman, would be a wise move by Carolina's front office.
Look for the Panthers to comb the free-agency pool for help with their offensive line and secondary, as well as some depth at other positions.
