When people discuss Calzaghe's career and his achievements, I don't understand why the fuck they have to bring up his punching technique and style? So what if he poor to watch and if he slapped like a girl, it didnt stop him from having a very good career or from beating som very good fighters. Actually the fact that he had to adapt his style in his later years as his hands were fucked, and was still successful, just shows how versatile a fighter he was. Anyways he had plenty of qualities, that are far less talked about than his bitch slapping. He had handspeed, stamina, an effective awkwardness and workrate, some very solid boxing skills and the ability to adapt very well in a fight.
As for his career achievements themselves, id personally consider him one of the best, if not the the best 168 pounder of all time, based purely on resume. I know several fighters more talented than Clazaghe passed through the division, but they didn't amass his body of work, He had plenty of good wins over Eubank, Woodhall, Mitchell, Lacy, Bika, Kessler and Hopkins, and that's some good names.
Calazghe's the kind of fighter who is either underrated or overrated, there rarely is a middle ground for any of his haters/fans.
