Luka Doncic might not be known for dunking, but he appears hard to impress as a Slam Dunk contest judge. Doncic hilariously called out a participant on Sunday's Jordan Brand event called "The One" in Los Angeles for dunking over "just" three people.After spending Saturday splitting time in Los Angeles and Las Vegas, Doncic was back in Hollywood to do some work for Jordan Brand. He was a judge at the Slam Dunk contest, giving out a 10 after one of the contestants jumped over three guys and dunked the ball with authority.But when asked after the dunk, "Luka Magic" jokingly said that he might be more impressed if the participant did it with four people."You gotta put four people," Doncic said.
