Under the Collective Bargaining Agreement, each NFL Club has the option to carry over unused cap space from the prior League Year. The Carolina Panthers will carry over $3,731,200 in unused cap space from the 2015 season.
This will give me the Panthers $3.73 million more in cap space they will be able to use towards their 2016 cap number, giving them a little more flexibility to possibly sign free agents and draft picks.
Under the current CBA, Clubs have minimum cash spending requirements. For the years 2013-2016, Clubs are required to spend an average of 89% of the Salary Cap over the four-year period. League-wide, Clubs must spend an average of 95% of the Salary Cap over the four-year period.
