Who hit the hardest: Ali, Holmes, or Usyk?

Agree with all points.

Resolve is extremely important as is being experienced and well drilled in fighting hurt.

I think it was who Ali described Foreman as having knocking him into the “near room” - and that he (Ali) had been there before so he knew not to panic and how to ride it out.

 

Holmes hit Spinks with loads and loads of flush right hands and he still finished the fight on his feet. It was pretty common for Holmes to stop people on their feet. He hit Frazier with loads of rights and he too finished upright, among many others. Gerrie Coetzee flattened Spinks multiple times in 123 seconds 2 years earlier. Ali when he punched with bad intentions had a notably crisper right hand.

 

Usyk hits harder than Hrg, those right hands were lame.

 

Ruiz may be 5'10 -James Toney was 5"9, Tyson about 5"9-5"10 Dwight Qawi was 5'5 - boxrec not accurate
