It’s the second-longest winning streak in NBA history, surpassing the 22 in a row that Houston won in 2007-08 and trailing only the 33 in a row won by the 1971-72 Los Angeles Lakers.
James scored 37 with 12 assists as the Heat won in Boston in the regular season for the first time in 11 tries despite a career-high 43 points from Jeff Green. The Celtics were without Kevin Garnett, who has the flu and a left thigh strain.
Paul Pierce had 17 points, eight rebounds and eight assists for the Celtics. But he missed a 3-pointer with 3 seconds left that could have given Boston the win.

In Atlanta, Darren Collison scored 24 points as hot-shooting Dallas set season highs for points in a half and a game.
Dallas led 68-55 at halftime and kept adding to the lead in the second half. Dirk Nowitzki, who had 22 points, hit two free throws as the Mavericks reached 100 with their first points of the final period.
Dallas made 57.3 percent of its shots (51 of 89). The Hawks also had a strong night on offense, shooting 56 percent from the field with eight scorers in double figures, but could come no closer than 11 points in the second half.
