Whether Cintron has mental problems or not, when he is in the ring he hits and hits harder than any welterweight. Williams doesn't have the physical presence or power in his fists to make Cintron quit like Margarito did. That being said, it doesn't seem like Williams is hard to "find" in the ring. Thus, if Mathysse was able to consistently score against Cintron, I don't see why Cintron can't consistently land against Williams. And if Cintron consistently lands against Williams, then Williams is going to get laid out. Of course, I think that Williams will pitty pat Cintron to death because he throws so many punches. And he seems to take a good punch. But in my opinion Cintron has a better than average shot to pull an upset.
