He was originally drafted out of Georgetown by the Celtics in 2007 with the fifth overall pick, but was traded immediately to the Seattle Sonics with others for Ray Allen and a second round pick that became Glen Davis. He followed the team to Oklahoma City and had some good and some bad years in his time there. But the Thunder felt they needed more defensive help down low and made the move for Kendrick Perkins last season.
While this is sad news for Jeff Green, it really does not impact the Celtics all to much. Some kind of replacement will be made though, just not a big one.
The Sacramento Kings also signed recently waived Travis Outlaw, the Detroit Pistons re-signed Rodney Stuckey, and the Chicago Bulls waived starter Keith Bogans and bench player Jennero Pargo. Jamal Crawford signed a two year contract with the Portland Trail Blazers.
