Hardest heavyweight punch of all time to score a k'o or knock down

[JT1]

I haven't seen many harder than Shavers on Holmes, how the hell did he get up.

No ranking below just contenders for hardest hitting
Marciono

Ernie Shavers

Mike Tyson

Ron Lyle
George Foreman said that Ron Lyle hit like a ton of bricks. I guess being stapped nearly to death builds up a little rage.

wow those are some great pic....I think that is the punch that made ali a re..re..re..******

Frazier on Ali was HUGE
Patterson on Johanssen
Marciano on Walcott was also HUGE

Dont be so disrespectful. Greatest man who ever lived, and you call him a ******? He gave us some of the greatest memories ever, even non-boxing fans. Most famous man in the world by far IMO, and loved.

Down goes Frazier, Down goes Frazier! To me the hardest punch would have to be Big George Forman's complete destruction of then heavyweight champion Joe Frazier. He kept getting up but he was just getting caught flush over and over.

the knock down was good but not the hardest punch knock down. Maybe foreman or liston had the hardest punch ever.

George Foreman then and I wonder what couldve been if David Tua had taken his career a bit more serious cause even now in the heavyweights ,he has a punch like no other, he had Lennox Lewis running in their fight

[stepmonster]

rocky marciano's overhand right KO of jersey joe walcott in their first fight. hardest punch in history IMO.
