It’s interesting to me that, while a lot of people paint the basketball development pipeline as being better in some countries they than the US, a lot of the great international players that have come along have credited some of their all-around skills to playing sports other than basketball when they were young.
Like Joker’s water polo history impacting his passing and guys who played soccer like Nash saying it helped with basketball footwork.
There’s a lot that goes into someone becoming a great NBA player and, IMO, the system they come up in is much less important than innate talent and work ethic.
