The judges didn't reward the guy who was more aggressive but the guy who landed the better strikes. That's inconsistent judging when you think of Kampmann/Sanchez or Garcia/KZ 1 or Garcia/Phan but I'd actually say it's the right way to score a fight. Vegh did just enough to convince the judges that he was the more effective striker.
