Cavs set playoff record with 41-point halftime lead in Game 2 rout of Celtics

— -- BOSTON - The Cleveland Cavaliers set a slate of records against the historic Boston Celtics franchise with their 130-86 Game 2 victory in the Eastern Conference finals Friday night.

Most stunning was setting the NBA postseason record for largest halftime lead, stretching it to 41 points with a J.R. Smith basket at the buzzer to take a 72-31 lead.

It also matched the fourth-largest road playoff margin in NBA history and was the widest margin of defeat for a No. 1 seed.

The Cavs scored the most points, and won by the largest margin in a playoff game, in franchise history. The Celtics' loss by 44 was the franchise's worst at home in the playoffs. It also matched the fourth-largest road playoff margin in NBA history and was the widest margin of defeat for a No. 1 seed.

"It's honestly just embarrassing," Celtics guard Avery Bradley said.

"We got our ass kicked," Celtics rookie Jaylen Brown said. "The defending champs swept us off the floor."

The Cavs won their 13th consecutive playoff game dating to last season, tying the Los Angeles Lakers from 1988 and 1989 for the all-time record.

LeBron James had 30 points on 12-of-18 shooting, his ninth consecutive playoff game with at least 30 points. That ties the all-time playoff record held by Michael Jordan, who did it twice. James also tied Kareem Abdul-Jabbar's mark of 10 straight games with 25 points and 50 percent or better shooting, set in 1970.

James has now personally won eight consecutive playoff games against the Celtics dating to the 2012 playoffs with the Miami Heat. That is the second-longest streak for any player in history against Boston.

"I'm a guy who lives in the moment," James said, downplaying the performance. "Our team is in a great groove, and I'm happy to be a part of that groove."

James' teams have now been up 2-0 in playoff series 21 times, he's gone to win the series in the previous 20.

The Cavs eventually pushed the lead to as much as 50 points and the eventual margin of 44 marked the second largest playoff loss in Celtics history after a 47-point defeat to the Orlando Magic in 1995.

"I just feel like we are in a great place where we're not looking for any excuses, not looking for anything to really motivate us other than for ourselves," said Kyrie Irving, who had 23 points. "We motivate each other."
