I see Collazo as the superior fighter to Quintana. I honestly think the only reason people think Collazo isn't all that is because he hurt his left hand early against Mosley because in those first three rounds he was doing better than mosley was in the fight. ONce he stopped throwing with conviction Mosley could do whatever he wanted and knew Collazo was throwing punches short. He has considerably faster hands than Quintana, and he has a much higher output and a much better chin. I think output bothers Berto more than technical skill because when Berto fights a technical fighter he fights more technical himself (like against Forbes) or when Collazo tried to box against Berto, Andre controlled him really easily on the outside with that speed.
