Chances are really high for about 95% that Lebron James will joined the 30,000 points party next season. They still have lots of remaining games before the playoffs and surely he can minimized the points required next year to achived that 30,000. For an average of 20+ points that needed next season, he can lowered it to 15+ points average if he will able to play at all games. But even if not, LBJ is not the type of player that have a low average points so definitely missed games can be covered.
if Lebron James will not suffer injury, he has a 99% chance to reach the 30,000 points next season.
He now has 28,316 points.
between regular seasons and playoffs this season will play approximately another 35-40 games and then at the end of the season he will reach about 29,000 points.
Next year will have about 100 games to reach 30,000 points.
I think he will come in first place currently occupied by Kareem Abdul-Jabbar with 38,387 perhaps in 2022!
