Paulie and Artem have no control on what the judges do.
This isn't a real sport yet and the judging showed that.
I rewatched the fight, and you could argue Paulie won 5-0. Outlanded him each round by a good margin.
Only notable thing was that Artem had that 5 second collision where he landed a couple worthless inside punches, and about two other grazing shots in 5 rounds and thats it.
At best, and I mean if you simply somehow minimize everything Paulie did and Maximize everything Artem did, you can only give Artem the last two rounds. Thats it.
