It has nothing to do with national affiliation. Pacquiao, Darchinyan and Margo have all clearly accomplished more than Calzaghe. By saying Calzaghe, you prove that you really don't lnow much about the sport, which is fine, but you probably shouldn't be posting in a boxing forum where knowledgable people are trying to have serious discussions while they should be working.
Calzaghe could not have done more, he is on top he beat Bhop and RJJ, maybe i will change my mind if Pacquiao schools DLH, but there is no chance in hell i would say Margarito had a better year than Calzaghe, i wont argue Darchinyan had a better or worse year than him, but he didnt beat on the level of fighter Calzaghe did.
Calzaghe - Beat Hopkins & Jones V. Klitschko - Returned after almost 4 years to dominate Peter Hopkins - Schooled Pavlik IN THAT ORDER.
Paul Williams. 3 wins in 3 different weight classes on 3 different networks; all by stoppage. Pac is up there for me as well. I'd put him no.1 if he beats Hoya.
