The wildcard would be the Collective Bargaining Agreement. Without an extension to the CBA, there will be no salary cap in 2010. And without a salary cap in 2010, a player with fewer than six years of service won’t be an unrestricted free agent next March.
So Edwards, who is entering his fifth NFL season, would be a restricted free agent. And the team that holds his rights will be able to retain his rights for 110 percent of his 2009 cap number, which as we understand it is in the range of $5 million.
