Why would it?
The man that everyone wants to see see Money fight, Manny Pacquiao, had already defeated Cotto back in November of 2009 at the MGM Grand in a 12-round bout.
While Cotto and Mayweather have never fought, there just isn't anything to gain in this fight—well, besides for Cotto's WBA Light Middleweight title.
While adding another title, especially one above his weight class, would be huge for Mayweather, everyone knows it doesn't matter until he actually defeats Pacquiao.
Unfortunately for Mayweather, that is how it is. Everything between now and the potential fight is just a sideshow, as fans await the true main event.
Money can continue to add belts and wins to his undefeated record, but he truly can't take the next step he needs to until he defeats Pacquiao.
According to ESPN.com, Mayweather may completely move on from the possibility of fighting Pacquiao, as he eyes a possible move to fight Sergio Martinez at the middleweight level.
However, rather than considering a drop in weight - or a demand for Pacquiao to step up - in order for the pair to square off, Mayweather's trainer and uncle Roger recently revealed a move up to middleweight could be on the agenda. That was later confirmed by the fighter himself, who has WBC champion Sergio Martinez in his sights.
The problem that Mayweather may not realize is no matter where he heads, everyone will keep coming back to ask him when he will take on the Pac-Man.
That is just how it has been and how it will continue to be. No fight will mean a thing for Mayweather, unless it is Pacquiao's name across from his on the card.
