Are LeBron James and Luka Doncic mere mortals or basketball stat-sheet-filling machines?

Coming off a Friday night game in which James and Doncic recorded triple-doubles in a thrilling overtime matchup won by the Lakers, the pair did it again in separate games Sunday.

Doncic posted 29 points, 14 rebounds and 15 assists in the Mavericks’ 131-111 crushing of the Cavaliers.

With Sunday’s performance, Doncic became the first player in NBA history to record at least 29 points, 15 assists and 13 rebounds in back-to-back games. In Friday’s losing effort, he put up 31 points, 13 rebounds and a career-high 15 assists.

Doncic, 20, also became the youngest player in NBA history to log consecutive 25-point triple-doubles, per Elias Stats Bureau. Doncic needed the second-fewest number of games in NBA history to record his first streak of 25-point triple-doubles (his 78th career NBA game). Only Oscar Robertson — who accomplished the feat in five games — did it sooner.

He joins legend Jason Kidd as only the second player in Mavericks history to have back-to-back 15-assist games.

For his part, LeBron had 21 points, 13 assists and 11 rebounds to become the first Laker to record back-to-back triple-doubles since Lamar Odom in 2006. Led by LeBron and Anthony Davis, the Lakers got past the Spurs 103-96.

With two steals, LeBron moved up to 15th on the all-time steals list with 1,945.

In Friday’s game, the future Hall-of-Famer recorded 39 points, 12 rebounds, 16 assists and four steals. He was the first Laker to clear the 30-10-15 mark since Magic Johnson in 1990. It was James’ 82nd career triple-double, and 30th with at least 30 points.

Sunday’s triple-double was the 83rd of his career, now in his 17th season.
