No. 1 Julius Erving (1976-1987)
Sure, Chamberlain put up some ridiculously amazing numbers, but Erving is Sixers basketball. Malone may have won the Finals MVP in 1983, but that was Erving’s team. The good doctor averaged 22.0 points, 6.7 rebounds, 3.9 assists, 1.8 steals, and 1.5 blocks with the Sixers and his worst season averages were 16.8 points and 4.4 rebounds in his final season. He was an All-Star all 11 seasons in Philadelphia and he leads the franchise in blocks, fourth in points, third in steals, fourth in assists, and seventh in rebounds. That makes him the best player in franchise history.
