I think Quintana has what it takes to defeat Williams. The loss to Cotto was the result of a perfect body shot not too many out there can deliver. However, it is going to be easy for Williams in the sense that his work rate will not allow him to lose the fight on points at all. I mean against Margarito, Williams landed like 22% of his shots, not a very good percentage all. Quintana will be able to stick and move very well, but unless he delivers a clear cut performance on points, he will not win against Williams. Thus, it seems like he needs a KO and I don't think that will be happening for Quintana.
