I disagree the 09/10 Pacquiao was ridiculous he was so so fast and so accurate with his punches, Mayweather would never have been able to handle that volume of punches with the power and accuracy of Pac, imo Mayweather will not retire undefeated i think he will lose in 2013 to either Guerrero, Rios or Canelo.
Floyd doesn't deserve to retire undefeated after ducking Pac in his prime!
You can't really make such a judgment based on Ricky Hatton, Miguel Cotto and Antonio Margarito.
It was not really that difficult to hit them as they all tried to fight fire with fire against Manny. Basically they made it a lot of more easier for him.
Floyd is a whole different story. If Marquez is such a difficult opponent for Manny, what does it say to you about Floyd? What Marquez can do in his defensive stance and counter-attacking style, Floyd can do it even better. How I said before, Mayweather is like a boxing machine. Too damn skillful.
I love Manny and I'll always love him for his prime performances, which were a gift for the sport of boxing. But honestly, I think his style and characteristics just fit Floyd perfectly. He'd shut him down with his intelligent way of fighting and win the damn fight on points. Maybe he'd get hit a couple of times, maybe he'd get rocked once or twice. But Floyd is not Ricky Hatton. He'd never get exposed for a KO punch like that.
What I mean basically - don't look at the Hatton/Cotto/Margarito fights and think that it'd be the same thing with Floyd. It would be not.
