It was redemption, plain and simple. Cotto has transformed more into a boxer and you could attribute that to his trainer who has alot of amateur training experience.
So, Margarito landed a shot and did nothing like the damage he did before. That to you indicates there was no wrapping? Sometimes the absence of a key factor indicates the presence of it in the past. Margo loaded his gloves against Cotto. He looked very similar to the first fight, it was just that Cotto wouldn't let him have the space he wanted.
10oz gloves, bs stoppage.. the fights proved that Cotto was able to bust Margaritos glass eye up after Pacs pass thats it..
