This past Friday, the Associated Press reported that 3-on-3 basketball could be included in the 2020 Summer Olympics in Tokyo.
The half-court basketball format — close in spirit to neighborhood park pick-up games — once seemed set for the 2016 Olympics...Now, FIBA believes men’s and women’s tournaments in 3-on-3 are even better suited after skateboarding and sport climbing joined the Tokyo lineup last year.
However, it seems unlikely that current NBA players would join the 3-on-3 teams in these first Olympics as it is a different style. This would most likely open up these positions to D-League and Euro League players.
