Castillo was his hardest fight and when you think it was only his 28th fight his 11th world title fight he had already made 9 defences of his superfeather title his 2nd world title at a second weight against the best in the devision at the time Castillo it shows how good Mayweather is compared to Hatton i suppose because he fought Castillo at the top of his game 5 year ago and now Hattons fighting the faded washed up version and thinks its a mega fight Floyd is p4p the best fighter in the world and with a win over De La Hoya and if he does'nt retire a couple more big wins he will go down as one of the best p4p fighters ever
