I don't understand why in the article, it states Cotto made a big mistake by circuling and hitting?

"Cotto was circling almost from the beginning of the fight and rarely stopped, a move that has been roundly criticized. Cotto wouldn’t accept criticism of his strategy, though he realized he opened himself to it by losing."

I thought this was the BEST strategy for Cotto and it was working out great for him up until he began to slow down as he came to the realization:

-that he was not prepared to circle and hit for a full 12 rounds
and
-Margarito's chin was made of Adamanteum (Wolverine bone structure) thus, could not be hurt.

For Cotto to win a rematch, he must go in with the exact same strategy with two minor modications. He must have it set in his mind that he will NOT be able to stop/hurt Margarito and most importantly, he must build his stamina to the point where would be able to do what he did for the first 6-7 rounds all the way through the full 12 rounds.

If so, I think Cotto wins an easy UD.
