You mean nationalism instead of racism, right?
There certainly seems to be some serious nationalism going on in the NBA this season. American NBA players just don't embrace the success of foreign born NBA players. This is a problem with the NBA's goal for globalization. Marketing the league internationally and having international stars carry the torch as the premier players in the NBA would be a financial dream come true for NBA brass and owners. US players though, they see it as competition for their jobs and their marketing opportunities.
Giannis may not have the support guys like Lebron or KD have in the US, but he brings a huge fan base internationally that the US fan base alone cannot compete with.
Jokic winning league MVP was another example.
The game is changing rapidly. We could have a foreign born league MVP and a foreign born defensive player of the year, finals MVP and leader of the NBA champions all in the same year. The olympics I'm afraid will emphasize this change as we will see the US team struggle.
The game has gone from 'look, there's the token Euro player who doesn't suck' to 'these foreign guys are running the league right now in Giannis, Jokic, Gobert, Embiid and Luka.
