He has dropped hints that he will fight Hatton over in England...As for Cotto sure he has a chance...but its slim.He was being hyped on his knockout power,and when I watched his last 2 fights I saw none of that.He throws body punches but they had little effect on malignaggi and urkal...so i see no reason why there would be a different outcome against mayweathers defense.
Mosley might have the best chance of them all...but he struggles against skilled boxers(not brawlers and boxer punchers).Mayweather gave mosley 3 chances to make a fight happen...now mosley has to chase mayweather.I see a mayweather fight being almost as lopsided as the mosley vs winky.
In order to beat mayweather...you have to catch him with straight hard shots and do some damage...otherwise its nearly impossible to outpoint him in the judges eyes.
