INDIANAPOLIS — Mac McClung went back to school to win his second consecutive NBA Slam Dunk Contest.

He asked Shaquille O’Neal to squeeze into McClung’s old high school jersey, then grabbed the ball out of the big man’s hands and leapt clear over him to draw five perfect scores on his final attempt Saturday night.

McClung compiled 98.8 points on his last two dunks, while Boston Celtics All-Star Jaylen Brown finished with 97.8.

“Shaq was so cool to put that high school jersey on, man, it almost made me emotional that he would do that,” McClung said. “When he put it on, he said, ‘You better not miss it.’ I said, ‘OK, I won’t miss it.'”

Unlike some of his previous attempts, McClung made this dunk on his first try and was rewarded handsomely by the five judges.

As a result, the high-flying, 6-foot-2 guard who plays for Orlando’s G League affiliate, the Osceola Magic, became the sixth player with two or more Slam Dunk titles and the first to win in back-to-back seasons since Zach LaVine in 2015 and 2016.

Hey Mac, gonna go for an unprecedented third straight title next year?

“I don’t know. We’ll think about it,” McClung said.

Lillard defends title

Milwaukee Bucks star Damian Lillard defended his NBA 3-point contest title by finishing with 26 points in the final round.

Lillard, who won with Portland last season, became the eighth player to win at least two 3-point crowns and the first since Jason Kapono in 2007 and 2008 to do it in consecutive years.

Lillard beat out Trae Young of Atlanta and Karl-Anthony Towns of Minnesota, who both had 24 points in the last round.

“I think last year it was a lower score to win. Like, nobody really shot the ball great,” Lillard said. “This one, I felt like everybody shot at a pretty high clip in the first round, in the tiebreaking round and the final round.”
