From the looks of the Mayorga fight one could think Berto would pull the upset here. Shane looked great against Margarito. But Berto is younger, faster and puts his punches together a lot better then Margarito does. Berto stands a much better chance of beating Shane then Margarito ever would. But then you'd watch Berto against Urango etc and say Shane should spark him. But I don't know, if they fight I can see Berto winning, I think Shane can too which is why if Mayweather comes up then Shane WILL fight him. Shane will only fight Berto if he absolutely has to. Otherswise big money payday for him
