As the book and exhibit make clear, splashy moves created on NYC courts still inform the NBA. “LeBron [James], at this year’s All-Star Game, dribbled down the court in a fast break and went behind his back [with the ball], like he was passing to his trailer,” said Bobbito Garcia, co-director of the New York basketball documentary “Doin’ it in the Park: Pick-Up Basketball, NYC.” “The defender went for the trailer and LeBron dunked it. Everybody went crazy. But I saw that move [on a playground court] in 1981. And it was probably done by somebody else here in the ’60s. That is what New York presents.”
