can anyone give me a good reason the USA would rob Kova but not Golovkin?

[////]

kovalev is an HBO fighter and top 5 p4p guy too...you act as if kovalevy was a poor darlys perez here or something...lol...ur out of touch with reality..kovalev was a champion...this was a fight between two top 5 p4p guys...not a prospect of a promotional company put in there with a "guy".....completely different

We know from the undercard the judges were either in Roc's pocket or very biased. The rest is speculation.
