While Denver Broncos GM George Paton and Sean Payton have built up a solid roster, there are still a few areas where they could use additional help. Fortunately, there are still some veteran free agents who could help the Broncos in exactly those areas. Of course, if the Broncos were to sign a free agent, that would mean cutting someone from the 90-man offseason roster. The Broncos took a significant risk with their linebacker unit by adding Dre Greenlaw, who is recovering from a serious injury, and pairing him with Alex Singleton, who missed most of last season with a torn ACL.
