LeBron sets the tone as Cavs blow Celtics awaySports | May 19, 2017
The Cavaliers were coming off a 10-day break but showed no signs of rust by going wire-to-wire at the Boston Garden arena.
"LeBron really controlled the tempo, really set the tone early," Cleveland coach Tyronn Lue said. "He's playing at a high level right now."
The Cavaliers built a 26-point lead in the first half and stretched it to 28 in the third quarter.
"I don't even think we played that great," said James, who also had nine rebounds and seven assists.
Tristan Thompson had 20 points and nine rebounds for Cleveland, and Kyrie Irving tallied 11 points and six assists.
Avery Bradley and Jae Crowder led the Celtics with 21 points apiece. Isaiah Thomas finished with 17 points but made only seven of 19 shots from the field.
