And the second factor is that as we know as the local and the champion Murata will have an advantage with the judges, and it will allow him to more easily retain his title, and that advantage is important when you are fighting someone like GGG.
There's no Japanese judge if I remember correctly. Do you think as a host country, they can influence the decision of foreign judges? What if Murata really scores lots of points. If there's something not right with the decision, we will see it clearly if we watch the fight.
Let's disregard the flaws in the result. Judges will have a fair result on that match and I'm willing to bet on it.
Even if there is no Japanese judge judging the fight they will be affected, now I am not saying that somehow the judges have been bribed to give the fight to Murata, even if we know that something like that can happen, what I am saying is that it is known that in team sports like soccer the referee will give a slight a advantage to the home team just because of the crowd.
And something similar can happen here, and when a fight is close even a single point can be the difference between winning or losing, and it is obvious that in that instance Murata will have an advantage over GGG.
