Fighters Whose Power Left Them When Going Up In Weight?

Good shout.

 

Donald Curry.

 

camacho punched well at 130 and 135 but at 140 147 and 160 he didnt punch nearly as well.

 

I think just about every puncher loses effectiveness when moving up to fight bigger men.

 

Maybe it's easier to list those who did retain devastating power despite moving up

 

Michael Moore could be argued, at LHW he was a legit 1 shot power puncher, at Heavy although he still had some pop it was no where near the same level.

 

Foster is the one I thought of right at the bat. The punches that put tough LHWs to sleep just made Ali and Frazier blink an extra time.

I agree with most of the mentions here except Hearns obviously and probably Leonard. Hearns was at his most destructive at ww and lmw, but he had enough power at mw to rock even Hagler and coming close to stopping a beast like Barkley. Leonard also showed plenty of pop as far up as smw - against Hearns and, especially, LaLonde.

He never tried to really hurt Hagler, which was the smart move after seeing devastating punchers like Hearns and Mugabi breaking themselves on that rock hard head. Think more or less the same can be said of Duran, who he had not managed to seriously hurt in his prime and who since then had walked through the best shots of both Hagler and Barkley.

 

until 175 he was still pretty brutal. the schuler knockout is one of my favourites

 

Julio Cesar Chavez lost some of his relative pop as he moved up. He expected guys to wilt in front of him and was visibly frustrated when they didn't.

 

That was a magic zone for Gomez,,,that 122 class. He was unbeatable in that division. he was excellent in the two higher weights he fought in, but he lost his cloak of invincibility.

 

Welter Mickey Walker fighting at Heavyweight.

 

very good example

God forgive me for mentioning this name in the same post as bob foster, but to a lesser degree ricky hatton didnt seem to carry it at welter as much as he did at lt-welter

 

Mayweather springs to mind

 

Mayweather just go brittle hands, he got very good power.
He's not the same anymore no, but he could still bang if his hands were stronger.

Not really going up in weightclass but Muhammad Ali had a KO ratio of 75-100% (Not sure how high but he was a very good puncher against cruisers) on sub 200 opponents. (Though you could say he fought ancient lightheavyweights)
But on 215lbs+ opponents it was just 33%

Joe Frazier had 100% KO ratio on sub 200 guys.
45% on 215lbs+

Earnie Shavers between 75 and 93% KO ratio on sub 200 guys.
47% on 215lbs+ opponents.
