What is the best knockout punch you've ever seen?

Rahman punch over Lennox Lewis

 

It was a controversial stoppage, but Oliver McCall's right hand that he landed on Lewis was pretty nasty.

It was more like a right-hook. I know Lewis got up and wobbled around, but I completely agreed with the stoppage.

 

Yes, Lewis Botha is a really classy KO. Power, accuracy, speed and punch variety all in a matter of seconds.

The Rahman KO less so. It is more a display of brute power with an opponent doing an impression of a mummy instead of a boxer during the 1-2.

 

walcotts left uppercut on ezzards chin....not getting up any shape or form

 

Forgot about Tyson vs Michael Jack Johnson
Easily one of the hardest right hands I've ever seen.

 

How about Mosley's left hook to Vargas chin in the sixth round of their rematch?

I know Vargas would get up and take a couple more punches before Kenny Bayless stopped it, but the knockdown was a crisp one, courtesy of Mosley setting it up perfectly, on his toes, using his jab.

 

McCallum-Curry
Hearns-Cuevas

 

Lots of good ones mentioned here.

Benitez - Hope came to my mind before I opened the thread.

 

Bobby Quarry vs. Dave Kilgore.

 

Donavon "Razor" Ruddock Vs. Michael Dokes
"The Smash" knocked Dokes out Cold for several Minutes.

 

Tyson's left hook on Carl Williams.

 

My top 3 in no order:

Marciano-Walcott I
Walcott-Charles III
Robinson-Fullmer II

 

Louis-Paychek

 

Weaver/Tate
Julian Jackson/Terry Norris
Marciano/Walcott
Walcott/Charles
Lewis Rahman...both

 

Julian Jackson vs Herol Graham.
