As a Puerto Rican, I don't know who to root for in this one. Those of you who have never seen Quintana should not base your predictions on Quintana's opposition. All you need to do is see his fight with Julio and that will tell you every thing you need to know about his chances against Cotto. Unlike Paulie, Quintana utilizes the ring very, very, well. He can also take a punch very, very well. He took some shots from Julio, who has fought at 154 and is known for his power. Quintana is always on the move, has great defensive skills and can either counter punch or become the agressor. He is a real pro and has ring savvy. Against Julio, I don't think I saw any clinches or a time when Quintana's back touched the ropes. The guy is really, really good. As for Cotto, he's going to have to rely on those boxing skills he had that have disappeared in recent fights. He can't come in there thinking he's going to out gun Quintana. Quintana is more accurate and has power. Cotto will be Quintana's most experienced opponent. I would predict a late round stoppage by Cotto, but I must say that if Cotto defeats Quintana, he has a great chance against Mayweather, because Quintana is a similar type of fighter in terms of ring savvy, skills, defense etc (remember, similar, not exactly the same). I will be more impressed if Cotto beats Quintana than if Quintana beats Cotto.
