I have to disagree with you on a couple of things here Rules. Ali, especially FOTC you're probably right, Prime Foreman, yes, probably early KO. But I don't think Holmes would have. He was more vulnerable in his early championship days to right hands. He held his left hand far too low, and this is something he did a little less post champion days. he was more confident in his early days, hence the left hand hanging, this prime Holmes would have been belted out sooner than 5 rounds. A prime Tyson is always going to be a serious problem for any age of Holmes. Just my tuppence worth.
Prime Tyson is going to be a serious problem for anyone,that doesn't necessarily mean he beats everyone ,but nobody is getting an easy night with him.
