Julius Winfield Erving II (born February 22, 1950), 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). He was the best known player in the ABA when the ABA-NBA merger joined it with the National Basketball Association (NBA) after the 1976 season.
Erving won three championships, four Most Valuable Player Awards, and three scoring titles while playing with the ABA's Virginia Squires and New York Nets and the NBA's Philadelphia 76ers. He is the fifth-highest scorer in professional basketball history, with 30,026 points (NBA and ABA combined). He is well-known for slam dunking from the free throw line in Slam Dunk Contests.
Erving was named to the NBA's 50th Anniversary All-Time team and in 1993 was inducted into the Basketball Hall of Fame. In 2004, he was inducted into the Nassau County Sports Hall of Fame. Many consider him among the most spectacular basketballers ever, and one of the best dunkers of all time. His signature dunk was the "slam" dunk, since incorporated into the vernacular and basic skill set of the game, in the same manner as the "cross-over" dribble and the "no look" pass.
