Gunnin' for That #1 Spot (2008) on Netflix

Plot summary

Rucker Park lies at the corner of 155th Street and Frederick Douglas Boulevard in Harlem, New York, a court where players earn nicknames and become legends and where Wilt Chamberlain, Kareem Abdul-Jabbar and Dr. J once played. On September 1, 2006, the twenty-four best high school basketball players in the country gathered on that court for the first Boost Mobile Elite 24 Hoops Classic. The film follows eight of those players as they approach professional careers, adored by fans and wooed by colleges and sneaker companies, while footage of the game, set to hip-hop, jazz and break beats, runs through it.
