NBA Scores: Heat win Ring Night, Mavs spoil new look Lakers' home opener

The NBA regular season is now officially underway after a three game opening night that saw the Miami Heat celebrate NBA championship ring night with a win over their rivals, the Boston Celtics. The nightcap was supposed to be a show case of the new look Los Angeles Lakers, but turned in to a deflating loss against the Dirk Nowitzki-less Dallas Mavericks.

Cleveland Cavaliers 94, Washington Wizards 84: The Cavaliers fans saw a career night from forward Anderson Varejao as he pulled down 23 rebounds, nine points and nine assists to lead the Cavs to a win over the Wizards. Washington rookie Bradley Beal scored eight points on 2-8 shooting in his debut.

Miami Heat 120, Boston Celtics 107: The Heat received their championship rings and then proceeded to score 120 points on the vaunted Celtic defense. All of this happened with LeBron James being limited to 29 minutes due to leg cramps that kept him out of much of the 4th quarter. James still finished the game with 26 points and 10 rebounds. Dwyane Wade finished with 29 points while Ray Allen dropped 19 points on his former team. Rajon Rondo had 20 points, 13 assists and seven rebounds for the Celtics.

Dallas Mavericks 99, Los Angeles Lakers 91: The Dallas Mavericks utilized a well-balanced offensive attack with six players scoring at least 10 points to defeat a Los Angeles Lakers squad that is obviously still getting used to each other. New addition Darren Collison led the Mavericks with 17 points. The Mavericks' bench was also key, outscoring the Lakers' bench 37-17. Dallas shot well across the board, making 47.1 percent of its field goals and 33.3 percent of its three-point attempts. The Lakers struggled to make stops all game and their offense seemed to stall after the first quarter. Dwight Howard had 19 points and 10 rebounds, but fouled out midway through the 4th quarter.
