I still say Walcott's KO of Charles tops the One Punch KO list..definitely at HW

I think it's my favorite KO of all time.

 

Won it with the best left ever thrown and then lost it to the best right ever thrown.

 

Did David Tua one punch out that legend John Ruiz?

 

I think you are right.

 

This could be another thread! "Devastating KO'S suffered by devastating KO artists ".

 

Apart from Walcott, Donald Curry always comes to mind for me.
His KO win over Milton McCrory and his KO loss to Mike McCallum.
(although McCrory was pointlessly allowed to attempt to carry on as he stumble around from the devasatating knockdown).
Two highlight reel punches for sure.
Interesting that Curry's opponents here had the same initials and similarly Scottish surnames.

 

Curry's left hook against McCrory was amazing, it was so short and quick. He just threw a jab and Curry countered with an explosive left hook that travelled a very short arc.

 

I love this one!
Definitely, one of the sweetest left hooks ever landed....

 

Pacquiao vs Hatton
and
Marquez vs Pacquiao

 

Lennox Lewis and Hasim Rahman both join that club.
Rahman won the champion on one big right hand, and lost it to Lewis by a big one-two if I remember rightly.

 

No argument here.

 

Love this ko
