I thought it was a pretty big upset. That being said, it was also one of the sloppiest fights I've seen in a while. I give much credit to Quintana for pulling it out, but honestly, I wasn't overly impressed with either guy last night. Let's be real, that was NOT the same Paul Williams who beat Margarito.I don't want to take away Quintana's credit, but I think Paul had a very off night. I think this also proves the dictum that styles make fights. Quintana had the style to beat Williams, but I honestly can't see him beating many of the top welters. I think Margarito would scrape Quintana, and unlike some of you I think Berto would have a good shot against him as well.
