McCullough, never knocked down and never flinched in 12 rounds with Hamed , P4P a bigger puncher than any of the others ever faced
Ted Kid Lewis Fought from Featherweight to Light Heavyweight had around 300 fights and was only stopped 6 times.
Lennox Lewis from the Vitali match being overweight clearly benefitted him and made his chin ultra sturdy, otherwise he would have gone down from Vitali's lethal right hand. Vitali has the 2nd highest KO% in history, mind you. and he landed some very clean shots on Lewis' traditionally shaky chin That version of Lennox was basically the most resilient version of Lewis there ever was. Green/ undertrained/ physically past prime Vitali would have stopped him eventually anyway, if it wasn't for the lucky cut and the corrupt and biased doctor and referee. Overweight Lennox was sturdier than ever but also very low on gas This is not the first time we see how being overweight increases your chin exponentially btw, just remember the comebacking version of Foreman. His chin was like 100 times better than it was in his prime
Vitali only had a 2 weeks notice for that fight and Vitali while heavyhanded isn't a one punch knock out artist
Not only did he face Hamed, he fought Morales, Zaragoza and Scott Harrison, to my knowledge he was never down once.
