We've had a varying array of supposed cap space numbers for the Panthers the last few weeks. Clayton's data indicates the Panthers are carrying over $3.6M from this season but based on current contracts the team is $11.8M over the projected 2013 cap:

On the negative side, the New York Jets are $19.4 million over the cap. The Dallas Cowboys are $18.2 million over, the New Orleans Saints $14.7 million over and the Carolina Panthers $11.8 million over.
As we have discussed in great length on CSR the next Panthers GM will have his work cut out to get this team under the cap without losing too many key players while also plugging some holes.
At the other end some teams have a ton of space; for example the Bucs have $31M available in 2013. But does that mean they will spend it all on high priced free agents? There is no salary floor so who knows, those teams might just fluff up their bottom lines instead of their roster.
Honestly I'm not too worried about being over the cap at the moment. Simply restructuring a few contracts like Smitty, Jordan Gross, Chris Gamble and DeAngelo Williams would probably get us under the cap.
