Cotto did the right thing, he was spitting blood, sweating blood and pretty much oozing blood left right and centre. It wasn't as if he took a couple of punches and quit. He took some serious licks. Margarito made him fight at a faster pace then he is used to and bust him up as he slowed down, he was pretty spent.

Of course it was okay for him to say 'enough is enough'. It was hardly Duran/Leonard 2.
