Most white Americans are discouraged from playing basketball because all of the stars are black. If the NBA promoted more white American players, like Kevin Love, David Lee, Steve Nash (Canada is still America), the kids looking up to them would at least feel like they have a chance to make a name for themselves in the league. As for the fact that most of the white star players are from European countries, it has to mostly do with the way the game is played over there. Its more like Olympic basketball with the wider lane and quicker gameplay. Those players come over here more skilled shooters and passers than there American counterparts. Americans are taught to play according to size and position while Europeans are taught according to their skill set. That why Dirk Nowitzki, Zydrunas Illgauskas and Yao Ming are better passers and shooters at their size than say a Luke Walton, Adam Morrison or Wally Szerbiak are at theirs.
