When fans think of NBA coaches, it is generally presumed that they will be born-and-bred U.S. citizens. The history of the game has always been in this country, so that is the way it has always worked.
But with the explosion of international players and the first generation now in retirement, it's only a matter of time before we see all sorts of foreign-born coaches on the sidelines.
They may wear Canali and Brioni suits instead of Joseph Abboud and Ralph Lauren, but there is no doubt that many of these international players turned coaches can—and will—succeed.
Jose Calderon, if he can bear being away from his beloved España, could be a top coach. He has all the requisite, nuanced understanding of how to run an offense, he is a fierce competitor and he has been leading players for years on both sides of the Atlantic.
Another benefit for any team that hires Calderon is that he may help attract international free agents, and his fluency in Spanish would be a big plus with Latino players.
