Top Fighters who struggled with a move up in weight.

[THE THIRD MAN]

I was reading a post recently that was talking about how Ricky Hatton was never quite as effective at 147 as he was at 140. Got me thinking of other fighters who were great at their favourite weight but struggled with a move up. Far worse than Ricky!

A few i can think of include

Bob Foster, great Light heavyweight champion, but got blasted out in his attempts at fighting Ali and Frazier at heavy.

Vassily Jirov, made numerous title defenses at cruiserweight but struggled to be more than a fringe contender at heavy.

Kelly Pavlik. Middleweight champ who never seems as effective when he moves up to supermiddle

Vic Darchinyan, did not look nearly as good at 118 as he does at 115.

Anyone else u guys can think of?

All good points there Eagle, Foster was a little stiff in that there was no Cruiserweight back then. Vic was well out of his depth against Agbeko.
I will say this, Roberto Duran lost all power and was never the same after No Mas. 147lb was his limit and apart from his win over Davey Moore at 154lb never showed the power and 'Hands Of Stone' we knew was there at 135lb.
He got blasted By Hearns and Hagler had little difficulty.
