International Boxing Research Organization’s Top 25 All Time Great Rankings

Usyk is great but no head to head beast many of his biggest fights are razor thin decisions Aura of invincibility must be cultivated to be a H2H best Most of the best had defeats... It's tough to cultivate an aura of invincibility when you lose.

i strongly disagree that jack johnson, dempsey and ketchel are better than floyd and manny p4p. no way. ketchel isn't top100 ever anymore. short reign (and life) with few defenses (only 2 great fighters defeated) isn't enough. it's not because of their era. terry mcgovern is from the same era as ketchel and he's clearly better. mcgovern knocked out reigning bantamweight, featherweight and lightweight champions of the world when there were 6 divisions and then light heavyweight was created. he knocked out joe gans in the meantime too. p4p terry is better than ketchel, dempsey (very inactive) and johnson (terrible reign) but people love heavyweights for some reason. i don't agree with some other people on that list (ross too isn't better than floyd and manny) but ketchel is just laughable. hagler, monzon and hopkins are better from his own division. salvador sanchez died even younger and he defeated 3 hall of famers. i don't see his name on the list.the names you mentioned plus Gene Tunney sounds like nostalgic bias or they were voting based on cultural impact their list did open my eyes to Mickey Walker though no discipline but a legend he'd show up to fights intoxicated and still win ultimately becoming an all time great

There can always be arguments made for or against those on or off the list. Several on this list that would not make my list. Doesn't mean they weren't good or even great, but not in my top 25.

About as great of a list as you can make

It's fully dependent on your personal concept of how "Greatness" is best defined. Most people's fall pretty close inside the bulls eye circle, but even in there you can have some variance in how the essential aspects chosen are weighted. Obviously, the IBRO posts up a sound list, but some fans might be a little off put by the heavy presence of old timers from before, say; the 1950s.would love to see their scoring criteria for example how tf is Eder Jofre well ahead of manny It seems a fighter’s cultural significance is a factor in their criteria
