There is no other business like the N.B.A. Its rainbow jump shots, rim-rattling dunks and heart-pounding drama are gleaming monuments to black America. Nearly 80 percent of league players are black. They are multimillionaire superstars, international icons and global purveyors of African-American excellence and culture.

Yet, for all of their success, most of them cannot look at N.B.A. leadership and see their own reflections. The vast majority of head coaches are white, as are most general managers and other league executives. Of the men and women with controlling interests in N.B.A. teams, only one, Michael Jordan of the Charlotte Hornets, looks like most of the players on his team.

This stark divide, and the familiar questions it raises about white people overseeing the toil of African-Americans, adds a layer of tension that ripples just beneath the glamour of the N.B.A. Much of what transpires in the league can be seen through the lens of race, especially this summer, when players upended the usual power dynamics by forcing a flurry of trades and transformational free-agent signings.

Consider the debate sparked by Draymond Green, the Golden State Warriors’ voluble All-Star forward, when he cast a wary eye on the league, its power structure and its racial tensions.
