My criteria in compiling this list is not fame, glory, historical impact on public opinion or financial success.
My criteria is solely based on how fighters perform, against whom and on the circumstances.
In compiling this list, I accounted for everything I know about each one of the fights I know about.
Things such as age and health conditions during each fight.
Cheating by one or both parties, including their teams, managements, promoters.
And so on.
Disagreements without posting an alternative do not deserve discussion, because dissing of a list without having an alternative and commitment to exposing it is trolling.
My list is based on a head-to-head criteria, with speculation about hypothetical fights between fighters that could not happen, or did not happen, plays a secondary role, but even my speculation is based on facts that happened and basic physical knowledge.
