you really believe half that stuff? ok. If Shaq played 40 years ago we'd be hearing tales about how he took one step and dunked from half court or something.
Wilt was a freak athlete too, maybe even moreso than Shaq with his speed and stamina(although I think Shaq in his prime was quite a bit bigger than Wilt in his prime, which makes up for some of the quickness difference). But Wilt was not always the dominant the playoff scorer Shaq was despite his athletic gifts. Partly because I think Shaq was a little more coordinated, had better footwork, and that is absurd given he was about 340 at his peak(00-01). Out of shape 380 pound Shaq was still somehow dominating people in the 02 playoffs. That speaks a lot to his innate athletic ability. And Shaq was ragdolling the likes of Ewing and Hakeem when he wasn't even at his peak.
Anyways, at the end of the day it is still LeBron for me. 6'8" 260 at that strength level with a 43-45 inch vert and guard like movement, coordination, and body control is just too much. I mean people think Westbrook is a freak athlete (he is) but LeBron has a higher vertical, better body control, speed difference is minimal, and strength difference is laughable. LeBron makes freak athletes look ordinary. Wilt wasn't that much heavier in his best years (around 290, and LeBron was probably closer to 270 around 2010) and he still couldn't move like that or jump anywhere near that. They measured LeBron's speed on the Iguodala block and for the 60 feet he sprinted it was faster than an NFL running back who ran a 4.36 40.
Not a question of belief, the stuff is documented. You can see plenty of footage of Wilt brushing off guys like Artis Gilmore, Walt Bellamy, Wes Unseld, etc like they are little kids. You can also see him grab the 6'7 240lbs Gus Johnson by the arm and throw him out of the frame like a sack of potatoes.
KAJ speaks highly of Wilt's athleticism, and that was a mid 30's Wilt. He played against Ewing and Robinson and Olajuwon.
Shaq was a fat after Orlando. Wilt was lean and had incredible stamina even at 310 with the Lakers. Shaq was fat at anything over that range.
Wilt stopped being a scorer for the back half of his career. Look at his scoring in the playoffs when he was still the primary option on his team. Wilt was only taking 9 or 10 shots a game his last few seasons with the Lakers. Wilt was basically playing like Bill Russel his last 5 or 6 seasons.
LeBron was dying of cramps because the arena was hot. He would have broke down in less than a season playing in the conditions the old NBA guys did. James is a great athlete, but he is far behind Wilt in strength and stamina, and only a little ahead in areas that one would think a smaller player would dominate.
