Eastern Euros own blacks every time. Look how they dominate the big divisions once they became pro. They have done the same in amateur boxing too.
This question is nonsense. Look at the Heavyweight division...
Klitschko, the best Heavyweight in the game, destroyed Thompson twice. Thompson KO'd Price twice. It's not nationality that wins fights. It's hardwork, dedication, and skills...
For amateur boxing I would say Ireland and America in 2nd place.
Altough I think its mainly the luck of the draw to which country produces great boxers.
Puerto Rico vs Philipinnes
Argentina vs Puerto Rico
Mexican/Mexican Americans vs African Americans (middleweight and below)
Euro vs African Americans (Heavyweight)
Who's got the edge ?
