Luka Dončić's meltdown and inability to control his emotions with officials will be his legacy from the NBA Finals.

The Mavericks' 3-0 series lead in Game 3 was a result of the Boston Celtics' unrelenting barrage of 3-pointers.

The Celtics made 56% of their shots in Game 3 were 3-point attempts, the highest rate ever in an NBA Finals game.

The Celtics have made 43 3-pointers in the series, nearly double the Mavericks' 22

The Celtics' defense has been a key factor in their success, with Doncic and P.J. Washington demonstrating the importance of consistent shooting.

Boston has seven players who have made 20 or more 3-pointers this postseason.
