The Mavericks won the third quarter by 19 points, their best point differential in a third quarter since Nov. 28, 2015 against the Nuggets. That night, Dallas outscored Denver 25-5 in the third quarter of a home win.
The Mavs have now won three consecutive third quarters by nine points, 12 points, and 19 points.
It should be noted that Dennis Smith Jr. played every crunch-time minute in this game. The rook had a much smoother performance tonight than against the longer, more athletic Boston defense. Credit to the 19-year-old for bouncing back and producing in this one.
