Did Cotto's nose affect him?

Of course it did, I also noticed blood in his mouth in the middle rounds and by the end he was spitting blood. Of course that affects you, it's impossible for it not to. It's not the sole reason Margarito one but definitely was a reason behind Cotto's loss. It's also no coincidence that when Cotto finally caved in, his face was at in it's worst condition of the fight.

Personally I think it was the massive bombs that affected him.
