Bad night excuse is BS. All boxers train for months to win come fight time. If you do not perform as expected during the actual fight, it's because your opponent's performance is better than yours. In Pacquaio-Marquez 3 fight, many viewers claimed Marquez won, just as there were also those who claimed Pacquiao won. There's a reason why aside from the 2 fighters, we have 1 referee and 3 official judges during the fight. They will determine who the winner is when the fighters fail to knock each other out. Pacquiao won officially, and whether you agree or not, we should all respect the decision. That's sports.
