Like 2-0 said, bleeding isn't anything new to Cotto, and he swells up in most of his fights. Pacquiao must have had plaster in his gloves, too, with the way he (Cotto) was beat up.
Also, Margarito must have had plaster in his face, since he took so many shots from Cotto and kept coming.
I don't see how you can use one fight (vs. Margarito) as evidence, and another (vs. Pacquiao), where he got beat up (physically) even MORE, and pretend like that doesn't matter.
Did Pacquiao have plaster in his hands vs. David Diaz? Did you see his face? Or maybe Jorge Arce had plaster in his gloves vs. Hussein Hussein, with the way his face looked.
Without the FACTUAL EVIDENCE, you cannot convict. BEYOND A REASONABLE DOUBT, remember? That's why OJ got off even though it was obvious he killed his wife.
If you were caught ATTEMPTING to commit a crime, TONY, would you expect to get the SAME sentence as if you had actually COMMITTED it? And after you were released, would you be cool with going back in, just because you MIGHT HAVE done it before? Even with no evidence?
