Here's a simple way to understand the difference between the GGG robbery and the Pac-Horn "robbery."

The vast majority (95%) of people think Golovkin beat Canelo. Pac-Horn was split 50-50. Therefore Golovkin was robbed and Pac wasn't. Popular opinion. Simple.

You should be wondering why you're in the tiny minority that thinks Golovkin lost? You should be re-evaluating your own scoring (motives), what are you missing that everyone else can see, not trying to convince the world that they're wrong.
