How much stronger was prime Shaq than an average NBA player who's 6'8"?

I'm 6'0" in shoes and to me the average 6'8" (barefoot) NBA player is so much stronger than me that I know I'd be murdered in an all-out fight.

Does the 6'8" guy look at prime Shaq like I look at the 6'8" player in that he's so much stronger it would be suicide? Or it is more like, yeah Shaq's stronger than me but I ain't terrified of him and he has a clear advantage in the end but I have a fighting chance, he's got only 5 inches and 100lb on me I'm not backing down if I have to fight him.

Also If Shaq had elbowed Isaiah instead of Lebron and drawn blood what would his reaction be? Would he have charged Shaq like that?

I'm not talking about impact or production on the basketball court - I'm talking a physical fight.
