people confuse heart with a great chin.

Margarito doesn't show great heart, he has shown a great chin. He can take the shots that others can't take. He was born with it.

Cotto is accused of not having heart because he took knees in the first fight. Which is a joke. He has heart, as he was getting beat the fuck up for quite a while before taking the knees. Cotto can't change the fact that his chin isn't very good.

Those that accuse Cotto of having no heart or guts need to watch the Clottey fight again. Cotto scored a knockdown in round 1 and had won at least 3 of the first 4 rounds on every card, meaning he was clearly up 4 pts. Cotto was cut by an accidental headbutt and it was examined. All he had to do was claim he couldn't see and it would have been stopped, gone to the cards, and he'd get a win. But he fought the entire fight with blood coming from the cut because he didn't want to win the fight by just saying stop it.
