I recently read an article that quoted Manny Pacquiao’s trainer, Freddie Roach, claiming that if the eagerly-awaited Mayweather-Pacquiao super-fight does happen, it could be as a career finale for both men.
During the Pacquiao-Bradley II post-fight interview with Larry Merchant of HBO Boxing, Manny stated that he thought he had two years left as a professional boxer, which means his career would come to a close around May 2016.
Intriguingly, Mayweather has three more contests remaining on his contract with Showtime beyond the Maidana bout. Assuming that Floyd remains undefeated and fights every May & September each year, his final bout under the Showtime banner would be September 2015… and a victory on that date would equal Rocky Marciano’s 49-0 professional record.
						
						
						
Trainer Freddie Roach is thinking that Floyd Mayweather Jr. will be making a mistake if he fights Amir Khan next, because he sees that as a fight that will lose money for Showtime/CBS. Roach believes that Mayweather needs to maximize the money he makes with his last 4 fights on his Showtime/CBS contract, and the way to do that is to fight Manny Pacquiao.
Over the past few years, performance enhancing drugs and money have been claimed to be the leading causes of preventing the Mayweather Jr. vs. Pacquiapo showdown form taking place.
Floyd Mayweather Jr. says that rumors of him supposedly fighting Manny Pacquiao in September or nothing more than a lie. He has no plans in fighting Pacquiao.  The rumors have also been dismissed by Pacquiao’s personal adviser Michael Koncz as being false. It would seem that some site jumped the gun and decided to come up with news of the Mayweather-Pacquiao mega fight without fact. 
Showtime President of Sports Stephen Espinoza doesn’t have a lot of faith than we’ll be seeing a fight between Floyd Mayweather Jr. and Manny Pacquiao in he near future unless Pacquiao bites the bullet and chooses to leave Top Rank. Espinoza sees that as being the issue that is keeping the fight between Manny and Floyd from taking place. Espinoza has no doubts in his mind that Mayweather would take the fight with Pacquiao immediately. 
Floyd Mayweather Jr. said this past week that he won’t bother fighting Manny Pacquiao as long as he’s still being promoted by Bob Arum of Top Rank. Mayweather simply doesn’t want to work with Arum for some reason. Golden Boy Promotions CEO Richard Schaefer is coming out saying that there won’t be a Mayweather-Pacquiao fight until Pacquiao is no longer with Top Rank. 
As expected, the two names that are involuntarily intertwined forever, Manny Pacquiao and Floyd Mayweather Jr. are back where they belong: in people’s heads and forum boards.
I can hear the groans from some fight fans already, those who have suffered enough over the games both sides have played with regards to thus far putting the stumbling blocks on making the fight the whole world (still) wants to see: Floyd Mayweather-Manny Pacquiao.
