Its funny that you mentioned it because, Winky actually sparred with Berto during his preparation for his fight against Ike Quartey, Berto was his chief sparring partner, and Berto more than held his own against Wright. Against Forrest, its impossible to judge that fight, Forrest definitely is super human, I mean look what Mayorga did to him. IMO Berto would give him a run for his money, and I am not saying Berto is the best fighter in the world, but he will be one of them soon, and stylewise Mosley will have terrible time against him. He hates fighting guys who are fast, guys who can jab, and nobody likes fighting a guy who is hard to hit, which Berto is when he is fighting normally(like against Forbes).
