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.
