We aren't here to prove his guilt. That will never be achieved, thanks to the incompetence of officials. We aren't trying to prosecute him. But, to assume his conduct was sqeaky clean prior to Mosley just because we don't have sufficient physical evidence is ignoring common sense. I think we can infer he wrapped illegally against Cotto/Cintron etc. without being out of line, as his entire record was compromised the day he cheated.
I think the point of the thread - and the point of the fight - is that the plaster made Cotto's chin worse. It is easier to damage someone's will with persistence when you are damaging there face with bricks.
