Rios saw how featherfisted Vargas badly hurt and almost KOd Bradley, so he went in thinking Bradley should be shot by now and that all he had to do was land flush once. Rios thought he could walk through Bradley's shots all night. Rios probably didn't train hard for this reason. If you had an iron jaw and was coming up against a featherfisted guy who almost got KOd by another featherfisted guy, you wouldnt train hard either.
Blame Garcia for Rios down fall the trainer must monitor the weight of a fighter Rios was dead man walking during the weight in and after a succulent meal of burritos and coronas he paid the ultimate price a lost by KO.
Yup, that's basically it. Funny he blamed the scale for not making weight. I like what he did to Maidana though...
