Dallas Mavericks stud guard Luka Doncic had it going early and often against the San Antonio Spurs on Monday night.

It really was something to behold from the 20-year-old guard, who finished with a 40-point triple-double.

Up 112-10 late in the fourth quarter, Doncic nailed a three-pointer to pretty much ice the game.

The reigning NBA Rookie of the Year ultimately ended the evening scoring 42 points, grabbing 11 rebounds and dishing out 12 assists.

Doncic joins LeBron James as the only players in the history of the NBA to put up a 40-point triple-double before his 21st birthday.

That’s some elite company to keep right there, and it has Doncic already looking like the best player in the Association. Just ridiculous stuff.
