The Boston Celtics met with Greg Oden on Saturday, according to the Boston Herald. Oden is attempting to come back next season after knee problems derailed the 7-foot center's career. "We wanted to talk to Greg to see where he is physically," Celtics executive Danny Ainge said. Oden was the No. 1 overall draft pick in 2007 by the Portland Trail Blazers, but missed his entire rookie season because of multiple knee surgeries. He played in 82 games before playing his last game on Dec. 5, 2009. "We're just finding out as much as we can and letting Greg know what we have here," Ainge said. "He's not ready to play now, but he's someone who's very interesting. The Celtics have lost point guard Rajon Rondo and Jared Sullinger to season-ending injuries in the past week. Oden has also drawn interest from the Cleveland Cavaliers and Miami Heat.
