2007 top NFL free agents

With free agency under way, here are my top 30 unfettered players in free agency. The group is comprised of unrestricted players and those who were released since the end of the season. It does not include restricted free agents or players designated as franchise or transition free agents. (Editor's note: This list is as of March 1 and will not include any players released at a later date.)
