ESPN's Adam Schefter reports free agent DE Antwan Odom is continuing to prepare for a return to the NFL. Odom has been out of the league nearly two entire seasons, but has been training for a comeback all offseason. Slapped with a four-game PED suspension in 2010, Odom was arrested for possession of marijuana in December, and was recovering from wrist surgery as recently as April. Two months shy of his 31st birthday, Odom will be a pure flier if he manages to land a contract.
