Ortiz weighed 164 against Mayweather and he was fighting at WELTER! Lots of guys drop weight to fight. Margarito fought Pacquiao weighing in at 165 and that was fought at 150. 154 would be just right.
Ridiculous. Weighing one ounce less means nothing in the real world, and it doesn't change the fighter at all.
martinez comes into camp above 180lbs and ortiz walks around at 165lbs, possible 12+lbs difference in weight cutting
