We have heard little this summer from Mavericks rookie Luka Doncic, the No. 3 overall pick in June's draft. The main reason we haven't heard much is that after attending a few Mavericks summer league games in Las Vegas in July, Doncic spent most of the following month with friends and family in Croatia.

Doncic returned to the United States three weeks ago, initially to attend the NBA Rookie Transition Program in New York. And where has he been since then? That was one of several questions The Dallas Morning News asked Doncic by phone late Friday afternoon, when we caught up with him in Seattle, where he was doing a promotional appearance for Destiny 2, the video game developed by Bungie.

"I've been everywhere," Doncic said. "I've been to New Jersey, New York, Los Angeles, Santa Barbara, Portland, Seattle. That's it."

But not Dallas. So when will he be here?

"Next week," Doncic said. Tuesday, to be exact.

Numerous Mavericks, including Dirk Nowitzki, Wesley Matthews and J.J. Barea, have spent much of the summer working out at the Mavericks' practice facility. Other Mavericks have trained elsewhere, including free agent signee DeAndre Jordan in Los Angeles. The Mavericks' media day is Sept. 21 and training camp begins the following day.

"I'm excited. Can't wait," said Doncic, adding that he got a place to live in Dallas shortly after his introductory news conference on June 22.

Mavericks coach Rick Carlisle planned to travel to Slovenia to spend personal time and do some on-court work with Doncic, but a family matter caused Carlisle to cancel.

"We will get to work now, when I get to Dallas," Doncic said.

On what?

"A lot of things."

Such as?

"Just first of all, get used to new coaches, new teammates. I think that's the most important thing."

Doncic, 19, didn't play on the Mavericks' summer league team because he'd had few breaks from basketball while playing for Real Madrid from 2015 to this June, when days before the NBA draft he helped lead Madrid to its third Spanish ACB League championship in four years.

The Mavericks' buyout of Doncic's Real Madrid contract wasn't completed until June 29. He then signed his three-year, $18.5 million rookie contract with the Mavericks, with a team option for a fourth year.

Doncic said he got plenty of rest in Croatia and recently ramped up his basketball activities, including several hours of training one day last week with Golden State star Stephen Curry. And where did that take place?

"That was in San Francisco," Doncic said. "Oh, yeah. I forgot to mention I was there."

On Thursday, Doncic tweeted a photo of himself clasping hands with Kobe Bryant, with a snake emoji and #mambamentality. Doncic said he and some fellow Nike basketball players were making an appearance on the Nike campus in Portland when Bryant showed up, to Doncic's pleasant surprise.

"I didn't know him personally," he said. "When I saw him it was just amazing. To see him, to meet him."

Friday in Seattle, Doncic and Chicago guard Zach LaVine played with DJ Dillon Francis (Doncic's playing partner) and rapper Vic Mensa (LaVine's partner) as they tried Destiny 2's new competitive mode, Gambit, which debuts next week.

How did Doncic do?

"I mean, all I can say is that my team won," he said.

WE ARE ALMOST LIVE!

Doncic was informed that Mavericks point guard Dennis Smith Jr. last season pronounced himself the best video game player on the team.

"That's not going to be true anymore," Doncic said.

Sounds like a challenge, one that Doncic and Smith can perhaps address when Doncic finally arrives in Dallas next week.
