LOS ANGELES: Darryl Dawkins, the former NBA star whose powerful dunks earned him the nickname “Chocolate Thunder,” died on Thursday (Friday in Manila) of a heart attack at the age of 58, his family said. In 1975, Dawkins was the first player drafted out of high school into the NBA — as the fifth overall selection by the Philadelphia 76ers. He went on to play 15 seasons with four teams: the Sixers (1975-82), the New Jersey Nets (1982-87), the Utah Jazz (1988) and the Detroit Pistons (1988-89). His dunks — which the player dubbed with names such as “Rim Wrecker” — were so powerful that he shattered two backboards in 1979. After his NBA career, he spent two years playing in Italy before joining the Harlem Globetrotters.
