Or you can criticize him:

That head butt in the third look somewhat intentional, and he has a history of head butting.

He behaved like a weasel at times during the fight. Like in the later rounds were he was flopping, after an accidental punch to the back of the head, in a cheap attempt to get Cotto penalized. He then did the same thing a couple of minutes later with a low blow. This was made worse by the fact that Cotto, behaved like a true fighter, never once complaining about the horrible cut he had to fight with.

And finally, and most obviously, he stopped punching in the last couple of rounds.
