There’s no doubt at all that the legendary Julius Erving had the ability and could play in any era, while being arguably at the top. He had the needed things to excel. He was among the most physically gifted players of all time. He was athletic, quick, explosive, could jump really high, run the court well consistently, had amazing hang time etc. His advantages weren’t questionable, because they were one of the main reasons of his excellence. Dr J also possessed arsenal of moves to score inside, soft touch and decent outside shot too. Julius retired as the fourth and sixth all time leading scorer in both regular and post season for a reason. He always put himself in great chances, thanks to his finishing and ability to get to the basket. Additionally, he was terrific defensively. In particular, his off-ball defense which was arguably second to none. He was notable presence at the lanes and was the master of the chase down blocks. He ranks high in those categories, as he ranks 12th and 13th on the all time list in playoff and regular season defensive win share. So, he did make a positive impact on that side of the court too. The bottom line is, that the Doctor could play at a world class level in any era.
