Julius Erving, Dr J, in basketball brought a revolution in style, I guess based on leaping ability and some center of mass awareness that made him seem to float or walk in the air. I'm not sure if he was the first from a general trend (on playgrounds, say) or if others adopted his style, but it really changed the game. Wilt, Russell, Kareem, and or Larry Bird had phenomenal abilities, but it wasn't something anybody could copy.
