I think the only one of these guys who should ever be mentioned in the top 20 p4p if he were to one or both of the other two is Roy Jones Jr. because if he can beat these guys at this stage in his career its more incredible than either of the other two winning against him and the other one. Hopkins sure he's older, but he hasn't put his body through the same process as Roy in that Roy went all the way up to heavyweight and back down. That destroyed Roy's body to large extent, and he has fallen way further from his prime than either Calzaghe or Hopkins. I don't think its because he got old and I truly believe if Roy had stayed at lhw he would still have only 1 lose on his record against montell, but besides that he would have continued to dominate guys. If Calzaghe wins ther can be a valid point that both Hopkins and Roy would have likely beaten him prime for prime, and he is the least battle worn of the three. He's had the least fights, he hasn't had to yoyo weight classes, he hasn't had very many tough competition. Regardless if Calzaghe wins against these two I still rate his career below either of them, and maybe in the top 50 all time, but not top ten. If HOpkins wins against both of them I would say he deserves top 30 because of his age, accomplishments, skills, and the route he went to achieve everything he did.
