City: Harlem, N.Y.
Out of all the players on this list, Herman "Helicopter" Knowings is perhaps the most mysterious. He balled at Rucker Park in the 1960s and 1970s, but never broke into the professional ranks. He was killed in a car accident at 37 years old, and with few images of him surviving, his tale is left up to urban legend. NBA Hall of Famer Bernard King once told the most well-known story of Knowings: "When I was in 9th grade, I saw the Helicopter, with my own two eyes, pick a quarter off the top of the backboard to win a bet, and I was in complete shock." You can figure where he got his nickname from now.
