Boxing is a fucking joke. Shitty one-dimensional sport that's on its way out.
MMA > Boxing
Manny > Mayweather
Go die in a fire. Not really, but yeah, fuck off. Boxing has one of the the richest histories in any sport probably EVER and it will continue. It will be around for generations to come. MMA will never, ever surpass boxing in the near future. Just because of boxing's history. There's nobody in MMA yet who has broke into popular culture like Muhammad Ali or Mike Tyson. I still think that's MANY years away. Try showing a random person in the street a photo of GSP or Anderson Silva next to Ali or even Pacquiao, who do you think will be recognized more? (This is all coming from somebody who watches just as much MMA as Boxing.)
Anyway, Mayweather looked slower than usual, his reflexes looked a little off and looks to be on the way down in terms of speed. If he really cares about that "0" so much, I would seriously consider hanging them up very very soon. 2-3 fights left at the most.
I think Mayweather is past his prime. Probably 4-5 years out of his physical prime. But his mind is as sharp as ever, his sheer boxing IQ got him through that fight. If he continues to push his luck against good fighters he WILL take a loss sooner than later. The Cotto fight was tougher than I expected, but of course I expected May win handily which he did. He only dropped 3 rounds according to two judges and 2 rounds according to another.
Manny is a tough fight and still has lightning speed and insane cardio. But he's been outboxed by Eric Morales and arguably JMM on multiple occasions. Mayweather can still outbox him but he needs to come into the shape of his life if he were to fight Manny. This Mayweather who showed up tonight would get worked by Pacquiao IMO.
Cotto looked good too, he was a drained figher against Pacquiao and had to cut a lot of weight. Against Floyd, he was much closer to his natural weight. Plus Cotto has improved as a fighter since the Pacquiao fight which is why Floyd had a tougher time with him than Pacquiao did.
If there's anytime Pacquiao can beat Mayweather, it's now.
Manny of ANY era would lose to Mayweather in his prime. You'd probably have to go back to the 80's to find fighters who could match up skill for skill with Floyd. (Sugar Ray Leonard, Roberto Duran, Aaron Pryor, Tommy Hearns etc.)
Below is Mayweather at his absolute peak when he was a lightweight. (130lbs) He fights 15 pounds heavier now, so obviously in 2012 he looks slow as shit compared to the fighter below.
