If Calzaghe had a big punch to go with his other skills he would be a legend.
Winning the 168 World Title in 1997, Calzaghe DID have a big punch back then.

At the time, Calzaghe was no volume puncher; he knocked peoples' brains out, but then his hands went bad on him, and he was forced to change up his game.
It's a credit and testament to his quality as a world-class fighter that he was able to totally change up his style and still compete at the top levels of a world sport. How many other fighters could do that?
Douchebags like kellerman were acting like Lacy was practically the uncrowned Champ in 2006, and all that remained was the novelty of making it official by knocking over Joe. I was certain Calzaghe would easily out-box him, but I had no idea it would be such a brutal, 1-sided beatdown.

Calzaghe was one of the best of the era circa late 90s to late 2000s.
