Could Margarito have been innocent?

i've been in professional boxers changing rooms for many years and each fighter deals with their nerves different ways, i've seen fighters who need to be kept talking to keep them from thinking about the fight and others who go into themselves and nobody is allowed to speak to them when they like that. so of course it is possible for him not to know about it and believe he trusted this guy to do his wraps without contemplating he would do something that could damage his career.
