Julius Erving, commonly known by the nickname Dr. J, is a retired American basketball player who helped launch a modern style of play that emphasizes leaping and play above the rim. Erving helped legitimize the American Basketball Association (ABA), and was the best-known player in that league when it merged with the NBA after the 1975-76 season. Erving won three championships, four MVP awards, and three scoring titles with the ABA’s Virginia Squires and New York Nets (now the NBA’s Brooklyn Nets) and the NBA’s Philadelphia 76ers. He is the sixth-highest scorer in ABA/NBA history. He was well known for slam dunking from the free throw line in Slam Dunk Contests and was the only player voted MVP in both the ABA and the NBA. Erving was born on this day in 1950.
