It's hard for Haney to become better than Mayweather because he lacks the power. Mayweather was a knockout artist during his younger years as a champion. Haney has zero knockouts and stoppages when he became a world champion. It's just difficult for light punchers to keep climbing weights because opponents are getting bigger and they can risk of getting hit just to land their own power shots.
Ryan while being over 3 pounds overweight was battling not just Haney but also the referee, the judge and there's also corrupt WBC not following the tradition of vacating the belt.
I agree, Floyd at 135 lbs was very different, start of the prime years of Mayweather, who wouldn't forget how he destroys Chico Corrales (RIP). And at 140 lbs, Haney still has no chin and with the power Ryan had at this weight, Haney can't handle it. The style though of Haney might have been pattern after Floyd, but then again, Floyd is way ahead of his time. Oscar says in the post-fight that Garcia can fight at catch-weights, as it seems the question is about him and Tank for a rematch. Garcia is really intelligent if he targets Fundora because I think he is the "weakest" of the Super Welterweight champion. I disagree though of what Derrick James says on Haney, that he can't return because of how Garcia beat him. Haney have learn a lot of lessons here and for sure he can box again and before he forget there is no belt on the line as Ryan come in overweight.
