Good espn article on Doncic...a lot more to it than what I quoted here...
The photo featured Dragic, then a youthful 21-year-old point guard prospect, and nine of his Union Olimpija teammates, hoisting the 2008 Slovenian League championship trophy. At the center of the photo was Sasa Doncic, a 34-year-old veteran forward gripping the stem of the cup as his teammates celebrated around him, confetti flying through the air. In the foreground of the photo stood Sasa's nine-year-old son in a green Olimpija jersey, gold medal around his neck, beaming with joy. Surrounded by his local heroes in Ljubljana, Slovenia, a small nation of only 2 million, the young ball boy was captured in a moment of bliss. His name: Luka Doncic.

"I don't want to give him a big head, but I think he's probably one of the best talents that I've ever seen, especially at his age," Randolph said. "It's unbelievable. Just for his size, the way that he handles the game, the way that he carries himself on and off the court. He's just so versatile. I mean, the kid can damn near average a triple double when he figures it out." Doncic's production given his age is unprecedented. Playing half the season as a 17-year-old, he was the only player in the Euroleague last season to average at least 15 points, eight rebounds and eight assists per 40 minutes. Although he struggled in the Euroleague final four, Doncic carried a strong season into Eurobasket play, producing like a 10-year veteran for a Slovenian team that shocked all of Europe on its way to a gold medal win over Serbia.

"I've seen a lot of players, they get hyped and then they kind of lose control," said Dragic, who is mentoring the 18-year-old like Steve Nash mentored him 10 years ago in Phoenix. "It gets in their heads. In a few years you don't even hear from them anymore. I don't think that's going to happen with Luka.
