[stuvin]

gatti v gamache was pure nasty.

[gustang1969]

[LittleBigMan]

Morrison vs. Mercer
It was quite scary the first time, but man, it is brutal.

most definitely

[butterfly1964]

muhammad ali vs. george foreman period. that fight proved he was the greatest.

[Imira]

Walcott-Charles - 3.

Yes! Allow me to add Charles v Layne 1, Louis v Buddy Baer 2 and Castillo v Coralles 2.

[Skydog]

Come on, the Joe Frazier KO of Bob Foster. Never seen a left hook land that hard in my life.

Come on, the Joe Frazier KO of Bob Foster. Never seen a left hook land that hard in my life.

In that case, I'll throw in Frazier's KO of Jimmy Ellis as well.

[VERSION1 (V1)]

Hearns-Duran....

Because of who was KO'd....& also because of the sheer beauty of the final punch.

that my pick

[American_Ninja]

Moorer vs Cooper, nasty uppercut to drop cooper. Great fight
