The Atlanta Journal-Constitution reports (via blog): Josh Childress is going back to Greece. The former Hawks swingman said he is returning to Olympiakos for the 2009-10 season and will not opt out of his contract and return to the NBA. “I still have some unfinished business to tend to,” Childress said by phone early Tuesday morning. “I definitely have unfinished business in Greece.” … The Hawks own his NBA rights and will continue to do so, provided they extend him a qualifying offer again next summer. His status as a restricted free agent allows the Hawks to match any offers made to him by other NBA teams.
