Here is Birds 60 point game. 36 shots he hit 22, 16 free throws, Over 60%. Jordans 69 in Boston wasn't done like this, I was there.
All of the best players could score like this if they take 40 or 45 shots like Jordan has done, doesn't impress me. Dominique was as athletic as any I've ever seen. Again, I don't think Bird was the GOAT he's the player I saw the most though.
Birds most shots were in that game 36, he wasn't a ball hog, like Jordan and Kobe who led in shots. This matters. Look at these stats no need to wonder why he got so many points.
