Yes, very obviously. 1. Roy Jones Jr fought three A-level opponents; Bernard Hopkins, James Toney and Antonio Tarver. Floyd Mayweathers win over Manny Pacquiao surpasses those scalps easily. 2. For different reasons, Roy fought many average opponents and missed out on some of the best challengers at the weights where he campaigned. Floyd has been fighting top opponets all of his career, facing the best in his own and several other weight classes. 3. Roy started getting knocked out by B-level fighters at an age of 35. Floyd beat a legit ATG at the age of 38. Anyone suggesting that Roy is ahead of Floyd DKSAB :silly Roy competes with Wladimir Klitschko as the third best fighter of this era, after Floyd (number one) and Manny (number two).
Yes, he's clearly above Jones. He has a better resume and also longevity. Weight jumping is similar for both (Jones from 160 to 190 and Mayweather from 130 to 154).
In reverse order: 3: Nobody can dispute that. Floyd has great longevity, and he's still at the top of his game. But although longevity is greatly important, there's also many other factors to consider when ranking someone. 2: Floyd also missed out on other fights, as almost every fighter does. The more weight classes you fight in, the more gaps appear on your resume. But you have to be fair and look at any and all circumstances as to why certain fights weren't made. 1: Complete nonsense. How can beating a 36 year old Manny Pacquiao eclipse those THREE wins of Roy's, all things considered? I think you're trolling for a laugh. I could put forward an argument for the Tarver fight alone to be better than the Pac win. Of course it wasn't a BIGGER win, because of the magnitude of the fight. It was the biggest grossing fight of all time. So it wasn't a bigger win. But I can certainly make an argument for it being a better win.
