how could have cotto won this fight? or win the rematch if there is one

[SSEVO]

cotto did everything right except for running outta gas and of course its bcuz margarito chopped him down. but cotto couldnt take a break. he caught him with tons of flush shots and he outboxed him but MARGARITO kept coming and coming. what could he have possibly done to win it?
i think there is only one way to beat margarito. its by overwhelming him with punches like paul williams did. just dont give him lot of chance to throw back and put you in the corner. what do you guys think?
