his father told him "you're losing"? How? from the crowd with a megaphone? Sr. did however say he thought oscar won the fight i'll give you that. Take that with a grain of salt Oscar was signing Sr.'s checks. PBF and Sr. were not seeing eye to eye at the time as well. but hey whatever floats your boat. He whooped oscar.
Mayweather's father wasn't in his corner for that fight and was actually at odds with his son. So what he may or may not have yelled from the crowd means little. You act like Mayweather was sitting there not throwing any punches. He threw less than Hoya but was outlanding him. Mayweather was landing the cleaner punches in most of the rounds. Anyone who knows the first thing about scoring a fight knows that is number 1 criteria for judges. Throwing flurries that are getting blocked will not win you the round if the other guy is landing the cleaner punches.
