Can Cintron beat Mayweather? Yes and so does Williams. Mayweather is a great fighter but he is not unbeatable. I say Cintron by KO and Williamson by wide UD
I know enough about boxing to know how fighters gets overrated. It is not Mayweather falult though. When Mayweather fought someone in his prime? If you know boxing you can answer that.
That is what I though you do not know the answer. And the answer is last time Mayweather fought fighter in prime in january 2005 Henry Bruseles, which is small 140 pounder B- OR C+ type of fighter. Now you get huge 147 pounders with huge power in Cintron agains highly overrated Mayweather who past his prime himself. Sounds like a big upset for regular boxing fan. But if you follow boxing you will know that it is not much of upset at all.
