The most popular outdoor basketball court in New York City is half the regulation size, offers no seating, and has sidelines bounded by a chain-link fence—but the summer league on West 4th Street in Greenwich Village has developed its share of stars and has become known throughout the world for another reason: Here, the only thing that matters is the game.

Inside the Cage follows the West 4th Street's summer league through a single season, chronicling its legendary history along the way. From 1970s playground legend Fly Williams to NBA veteran Anthony Mason and L.A. Lakers guard Smush Parker, three generations of players have mastered their game at West 4th Street. And the Cage itself—located in one of the wealthiest neighborhoods in America and frequented by men from the Bronx, Brooklyn, and Harlem—proves that talent can flourish even in the most unlikely places.
