An early morning return after an emotional win in Miami, followed by an overtime victory against a well-rested Atlanta team. Nothing seems to stop the charging Boston Celtics lately. Paul Pierce overcame a miserable shooting game with a key jumper in overtime and Rajon Rondo finished with a triple-double with 20 assists, 10 points and 10 rebounds to lift the surging Celtics to an 88-86 win over the Hawks on Wednesday night.
