Just make it U23 for basketball like soccer.
Olympics for basketball is the most important international tournament like any sport except for football, tennis or boxing, football was always a secondary thing at the Olympics even before the first World Cup in 1930.
While U-23 Basketball will be something like Football U-14 equivalent, even so, football at the Olympics isn't justified except for the 2012 Tournament where 1.5m attended, its more like an extra thing among serious competitions.
Also, the NBA players weren't always present at the Olympics and USA won the gold with college teams.
Michael Jordan won it in 1984 just days after being drafted by the Bulls as he was still in NC College.
Not sure? The gold medal is by far the most important title for them, World Cups are secondary and get minor attention compared virtually anywhere.
Football is just an exception while Rugby Union will be in the same category if it had a Olympic event. Football at the Olympics remains the most important for the women's event.
Basketball depends on NBA, as long as NBA players keep going its keeping the international stage alive, if not, it might as well die for good.
