RJJ today can beat Calzaghe no doubt about it!!!!!! RJJ would stick and move even though RJJ chin is suspect today Calzaghe does not possess the one punch knock out power to Knock out Roy HE CANT DO IT!!!!!!!!!!!!!!!!!!!!!! tarver has a punch the road warrior has a punch but not calzaghe!!!!!!! Calzaghe would have to rely on accumalative punishment on Roy,he is still to quick for Calzaghe and Roy would be brave and not to shy to punch more Matter of fact Roy can use this fight to get back some respect Roy would Toy with him
