Fair points and a well constructed argument Hitmandonny BUT I don’t think joe has ever really been a KO artist, certainly not a one puch KO artist, most of his stoppages have come through volume of punches…TKOs. He still hits hard, he hurt Kessler.

Hitmandonny who has the best physical game in the sport in your opinion then? Mayweather? He has shown physical fragility over the years particularly regarding his hands

Also I don’t know how you can judge that his punch resistance has diminished, he has been in with some big hitters recently in Kessler and lacy and stood up superbly.

Judging his power on the Kessler fight is difficult. Kessler has never been down as an amateur or a pro. Bika has never lost by KO even to a regarded heavy hitter in Lucian Bute. Lacy has shown to have a great chin aswell.

The bottom line, most championship fights between the very best boxers end up going the distance like jones v Hopkins, mayweather vs de la hoya, calzaghe v Kessler. This is why mayweathers record doesn’t have the best KO % as he has fought so many championship bouts, this is why calzaghes KO% in recent fights has been lower than his average, he has been fighting the very best opposition, most good fighters have good chins. Mayweathers lowish KO% doesnt mean he cant punch, look what happened to hatton. In the end hatton’s assumption that mayweather couldn’t hurt him was a fatal error in his tactics and preparation. Hopkins wont make that mistake against Calzaghe that’s for sure, if he does he will end up on his back!

I think its hard to say that calzaghes power has diminished because of his hands. When they are broken or hurting then yes, he takes something off his punches consciously. Although, I don’t believe calzaghe takes weight of his biggest punches in a fight based on fear for his hands. When a fighter goes for the big shots there is no time for doubt or consciously only putting say 90% effort into your powershots. The day that happens the day you lose and end up on your back. His hands were fine against Kessler and I am sure he put everything into his shots, any apparent loss of power probably wouldn’t have anything to do with his hands. People said the same of mayweather and his hands and look what happened to hatton. A fighters natural KO power is probably the last thing that he loses as he ages. Certainly its always a threat in the first few founds while a fighters stamina is still there.
