On their very best night who wins the all time heavyweight prizefighter competition?

[BIG H]

So what I mean is, they all meet each other on their very best night over 12 rounds. Take into consideration all factors, such as height e.t.c; e.g even if you think Rocky Marciano is the 'Greatest' heavyweight of all time, you surely would not expect him to beat Vitali Klitchko!

I think that some names that would not appear on the top 10 ATG list, would have a shout using this criteria.

Thoughts?

This is not about longjevity or legacy etc etc it's about one-on-one fights on their very best night.

This is a VERY good topic and I love the way you have it going about....You are 100% correct using the method stated many not ATG hwts can be mentioned.....

Shavers can be a candidate just due to his power being enough to starch anyone on any night...Walcott a former chasmpion who could be a dark horse....Marciano on the stamina factor could wear down any HW......

Personally I like Jack Johnson as a favorite Jack was amazing and 75yrs ahead of his time in skillset when compared to others of his era....Sam McVey was damn dagerous!!!!

I can't even begin to choose who would truly win after thought so many names so good on certain nights.....The Buster Douglas that beat Tyson would be a canidate for certain

Yeh, agree on Buster Douglas. I mean, he was generally a lazy fat bum, but he had talent and on that one night in history he was phenomenal!!
