Unlike most New York streetball greats, Jack Ryan didn't take his talents uptown to Rucker Park. Instead, he stayed at John Jay High School and East 5th St. Park in Brooklyn to work on his tricks and shooting. NBA Hall of Famer Chris Mullin once called Ryan the greatest shooter he'd ever seen to not play in the NBA—a claim that can easily be backed up. Just check the tape. He won ESPN's City Slam three-point shooting championship back in 2005. Ryan currently tours the country performing basketball tricks at halftime shows and parties.
