Has there ever been?

theres also a claim that if you watch the film his wife leaves in like the 9th round which indicates to johnson that she recieved the payoff

Why wouldn't she just stay with the payoff and finish watching the fight.

cuz her leaving was supposed to be the signal to him that she got paid and he could take the dive

If she left in the ninth, why the hell did he stay up til the twentieth?
I think Johnson was well past his prime by this fight, he would have battered Willard 5 years earlier. IMO he was knackered after a long fight on a hot day against a guy he couldn't impose his strengh on, and fell over of exhaustion more than being knocked from his senses.

On the subject of the post, I think Joe Calzaghe said it best when he said that fighters aren't robots and they are inevitably going to have off nights, or maybe lose focus for just a second in one fight. Many fighters come close, psobably the closest are ricardo lopez (though I've only seen his record) and Roy Jones, who would have fit the criteria except for one tiny lack of focus against griffin, and if he'd retired after ruiz
