Please get your facts right Sir. I did not say was the best ever I said he is arguably the most complete fighter ever. He may or may not be the best ever that will be determined when his time has passed but he is doing a great job of putting himself in the mix with the best of the best such as Duran, Charley Burley etc. I am not saying going up in weight is unique but very few fighters can achieve like those you have correctly mentioned and the great Henry Armstrong otherwise known as Homicide Hank. Mayweather has gone up all the way from 130 to 155 beating men like Castillo, Corrales, ODLH, Judah, Baldomir, the Little Big man Sharmba Mitchell etc and won. That is the point. Marquez is smaller but Marquez also happens to be one of the very best fighters out there, Marquez did not lose because of the weight the reason Marquez lost is that even though he is a great fighter he was up against someone who was better than him at everything that makes Marquez great.
