Pretty boy lost to Castillo, absolute robbery. Great defensive fighter but he's unbeaten more due to management and that decision than his skillset, Pacman in his prime beats him all day and Floyd dragged out that fight to avoid pacs prime just an opinion like assholes appreciate everyone has one.
Jones similar avoided a lot of guys when he was on top, but amazing skill set. Would have liked too see him fight calzaghie collins etc in his prime.
Mayweathers record is manufactured. he was a very good boxer, especially early in his career. He had some pop and good speed, reflexes as well as technique and fundamentals. I hate the guy with a passion but he was a very good boxer. He did not take many real risks in his later career. Always fighting guys too small or too old. He fought Canelo before Canelo was really experienced, he had a lot of fights but not many at the upper level. He beat the crap out of Diego Corrales but Corrales was fighting under a suspended prison sentence. His mind wasn't right, he was going to jail shortly after that fight IIRC.
Now RJJ was a physical marvel. Really otherworldly speed, reflexes and power. I am absolutely certain he was juiced to the gills early on in his career. At 154 & 160 his power paralyzed guys. His knock out of Art Serwano was scary. His speed allowed him to have fairly average boxing skills, he made cardinal mistakes all the time but was able to get away with it due to his speed and reflexes. But as he got older and he lost his speed and reflexes, he didn't have the fundamentals to beat even average boxers. And he pretty poor punch resistance. He was never hit really flush in the first 15 years of his career.
