IYO, who else in heavy history could have destroyed frazier in 73?

Theres quite clearly a lapse

 

Incredible in this day and age people can argue over something proven right there in front of them.

The punch itself did not "lift" Frazier off his feet.

There is an oh so obvious delay between the punch and his feet lifting off the ground.

There are only two possible outcomes imo.

One is that the punch caused a delayed twitch/spasm which i used to think but now doubt.

More likely tho it is a reaction to him being knocked sideways. His upper body is belted sideways but initially his feet stay planted. His left foot then lifts. I fully believe he then reacts with a jump sideways off the right foot in an effort to counter his upper body falling - it's an effort to regain his footing. It fails.

You can argue whether this action to regain his footing is reflexive/instinctual or other.

But for me it's a case of trying not to leave his feet.

 

MAybe as an outside pick, someone like Tua even?

 

I'd definitely say David Tua, and I'm going out on a limb here, but Deontay Wilder. Whatever you say about him, the guy can hit like hell.
