Paul Pierce is the hero: Another night, another fourth quarter rally by the Boston Celtics helped them to a victory, this time over the Dallas Mavericks 99-92 in Dallas. Paul Pierce led the comeback for the Celtics with 18 of his 31 points coming in the decisive fourth quarter. Ray Allen’s thumb was fine as he scored 20 points while Rajon Rondo picked up his second career triple-double with 19 points, 15 rebounds and 14 assists. Kevin Garnett added 16 points for the Celtics who lost coach Doc Rivers to an ejection in the 3rd quarter. Dirk Nowitzki led all scorers in the game with 37 points. Josh Howard chipped in with 17 points while Antoine Wright had 10. With the All-Star Game this weekend, the Celtics are off until next Thursday when they will take on the Utah Jazz in Salt Lake City.
