Luka Doncic is now part of the Dallas Mavericks, and none other than Dirk Nowitzki — the face of the franchise — welcomed him.

Via his Twitter account, Nowitzki tweeted to the 19-year-old to welcome him.

After a while, Doncic himself replied, calling Nowitzki a “Legend.”

The Mavs got Doncic via trade from Atlanta Hawks for Trae Young —  selected 5th overall.

Doncic admitted that the Mavs have been talking to him, per ESPN's Tim Macmahon:

“I've been talking to a lot of teams, but especially Dallas, they've been talking to me, they were so nice to me, and I'm glad you know … I'm just happy to be in the NBA. I'm just happy to be a part of that,” Doncic told ESPN after learning he would be sent to Dallas.

Analysts have tagged Doncic as the most NBA-ready in this year's batch of incoming rookies. He has played professional ball since 13 years old, quickly rising as one of the top players in the Euroleague.

Aaron Jackson of the Houston Rockets got an opportunity to play against Doncic. He was just 16 years old back then, but the talent was pretty apparent. Per Alex Kennedy of Hoops Hype, Jackson said:

“One of Doncic’s first Euroleague games was against my Russian team a few years ago, CSKA Moscow. We had no specific game-plan for him, no scouting report for him. But we knew he was young, so we decided that we would try to intimidate him. We went under every ball screen. The first time he realized it, he didn’t shoot. The second time? He fired a deep three. All net. Next possession? Same thing. He was 16 years old, playing against CSKA! After that game, he never looked back!”
