Numerous players remain unsigned through the first several weeks of the NFL free agency period.
Reasons varying from age, lack of production, injuries or character concerns are keeping most of the remaining players available.
Another factor, unique to the 2010 offseason, is the new collective bargaining agreement(CBA) on the horizon. Teams and players are weary of all contract negotiations with a potential lockout for the 2011 season and potential changes to the CBA.
All that said, there are several players who inexplicably remain unsigned heading into the 2010 NFL season.
