Golden State Warriors rookie Yaxel Lendeborg had an extraordinary NBA debut as he jawed with Luka Dončić and admitted he had largely been exposed to the league through highlights before turning professional.

Lendeborg was given the task of guarding the Los Angeles Lakers star for large parts of Wednesday’s game, which Dončić’s team won 127-105.

However, Lendeborg said he “lost all respect” for Dončić’s quest for foul calls during the game.

“I had a lot of respect for him [because] I didn’t really watch the NBA much,” Lendeborg said. “I just watched highlights and seen him kill people. But being in it firsthand and seeing all the whining and complaining, I lost all respect.”

Lendeborg was the No 11 overall pick by the Warriors in this year’s draft after helping Michigan win the NCAA Tournament. He had early success shutting down Dončić, but the six-time All-Star went on to score 28 points in the Lakers’ victory.

In the second quarter, Dončić was fouled by Lendeborg after a pump fake and celebrated in front of the rookie.

“You get the foul call. Congratulations, bro,” Lendeborg said. “Then you talk to me like you did something great. C’mon, dog. That shit is weak. It kind of threw me off because I have so much respect for him. Gone, man. Gone.”

Lendeborg was given a technical for jawing at Dončić. “I was telling him he sucks,” Lendeborg said. “He can’t score on me. You talk but you can’t score on me. I said it the whole game. I said a couple cuss words, obviously. That’s why I got the technical. But I was letting him know.”

Lendeborg seemed unimpressed by the league in general after his debut.

“I guess this is what the NBA is like, man,” Lendeborg said. “A lot of flopping, a lot of foul baiting, a lot of praying to the refs, man. Interesting first game for me.”

Lendeborg had already made an impression before his debut. He admitted he used to hate his new teammate Stephen Curry because he was a fan of one of his playing rivals, Kyrie Irving. Warriors veteran Draymond Green, who is not shy of expressing his own opinions, had no problems with the rookie’s attitude.

“In this league, everybody always says, ‘Oh, there’s certain guys you got to respect,’” Green said after Wednesday’s game. “I ain’t come in the league like that. Everybody will say, ‘Oh, the rookie learned his lesson.’ What’d he learn? The next time he see him, go at his ass again.”

For his part, Dončić said he was trying to stay out of trouble.

“He was talking crazy,” Dončić said. “But I wasn’t trying to talk back. This season, I’m not trying to get techs.”
