look, for the 1st Margarito showed his pain tolerance declined, Shane made him backup. Once the pain tolerance of a fighter drops that depends solely on there pain tolerance to get them through a fight there done! his iron chin was cracked, He made people tired from banging his chin and coming back with Iron knuckles but that Iron chin is gone and margo is slow as it get, he will die in that ring
Margarito is finished man. That Cotto-Margarito fight ruined both fighters. Shane put a beating on him. No one is trying to watch a fight where they already know the outcome.
