Kareem had his unstoppable Sky-hook. Olajuwan had the dream shake. O'Neil has moves, but how many times did he have to execute against a player of comparable size and strength? Wilt had so many moves, there was no one signature one that defined him.
How many times did O'Neal have to execute against a player of comparable size and strength? PLEASE!!! Let's start the list (over the course of Shaq's career): Hakeem, DRob, Ewing, Zo, BMiller, Ostertag, Ilgauskas, Ming (taller than Shaq), Oliver Miller, Nesterovic, Duncan, Polynice, Bradley (also taller than Shaq) -- I COULD go on, couldn't I? The league has a TON of 7 footers today! I didn't say that all of these players were good -- simply answering your question -- how many times has O'Neal had to execute against a player of comparable size and/or strength?
Now, let's start the list on Wilt -- when was it that he had to execute against a player of comparable size and strength? It wasn't until VERY late in his career! There were a few 6'10"/6'11" guys that came into the league a couple of years after Wilt did -- but that was after Wilt had already set his records, wasn't it?
Again, even those teams that had a 6'10" or 6'11" guy -- what was the rest of the roster like? SA has two starting 7'0" players -- Wilt NEVER played against ANYTHING like that, did he?
Go back and check roster size because Wilt didn't play against ANYONE remotely of comparable size and strength until Kareem came into the league very late in Wilt's career. Also, remember that Wilt came into the league after playing pretty much professional ball with the globetrotters -- he was ready for the NBA and he set his records at that point before the league had any other big men.
Shaq is as strong or stronger than all of these players, and taller than most but Yao, Illguaskis, Sabonis, Bradley.
Wilt played against Willis Reed, Bill Russell, Nate Thurmond, Zelmo Beatty, Kareem, Bob Lanier, Walt Bellamy, Wes Unseld, Dave Cowens, Elvin Hayes. Every one of those was a hall of famer.
Wilt played most of his career in an era with an average of about 14 teams (from 9 to 17), Shaq in an era of about 28 teams. Shaq played many fewer games against the best centers, more against Bradley, and Polynice.
