Margarito very likely had loaded wraps for Cotto and Cintron.

Cotto was busted up in the first round.

Cintron says he's never felt a punch the way that Margarito hit him. Cintron hasn't been stopped by anyone else, (Martinez should have been, but he still got up)

Loaded wraps did not help him throw 100+ punches a round or improve his chin, but it made him much more dangerous.

Loaded wraps is directly cheating, and you would know that your hands felt a little different.

Tito was doing it also, pretty much a proven fact. His Dad said they always wrapped the same way. It just wasn't as obvious, his was made into a cast by getting it wet.
