Takeaways Heat: Keshad Johnson made his NBA debut and scored two points in seven minutes.

Celtics: Have not lost back-to-back games all season.

Key moment Pritchard, who hit two half-court buzzer-beaters in the NBA Finals, beat the third-quarter buzzer on Monday night when he dribbled through the lane and sidestepped defender Pelle Larsson and laid in a left-hander off the backboard to give Boston a 22-point lead — their biggest in the game to that point.

Key stat Pritchard became the first NBA player this season to score 20 or more bench points in four straight games. He's the first Celtic to do it since Isaiah Thomas in 2015.
