Wembi was born January 4th, 2004. The Spurs will play 31 games before January 4th, 2024.

LeBron James scored 625 points before turning 20. (Kobe Bryant is 2nd with 539 points at 19 years old)

To score 626 points and pass Lebron, Wembi will need to average 20.2 points playing all 31 games.

He could also play in 27/31 games and average 23.2 ppg.

In my opinion, this is very doable, as he averaged 21.6 ppg in France, and 19.3 ppg in 21 mpg during preseason.
