Past players like Cousy and Pistol definitely had a better "feel" for the ball, as if it was an extension of their bodies, but I think Irving's mix of handles, first step, quickness, and acrobatic finishing has never been seen before.
Pistol Pete had an otherworldly feel for the game. His vision was tremendous.
EDIT: I just realized I spelled Bob Cousy's name wrong. It's been a long week.
