I think Heungkuk lost the match because of their receiving and errors.
I did see some clips online of the other Heungkuk setter PARK Eun-Seo setting some balls that were either low or weak.
Well you know what I'm referring to, the completely worship like culture of k-volleyball
It will never be the attackers fault (not that I think it was for this match) but because of that the blame falls on the setter. When they win its because of the attacker, when they lose its the setter.
Dasol was never fantastic , but manages to remain average not horrible, and Eunseo is still new. It's a pity Hyejin got injured.
It was a pain to watch the match though, I'm not sure if anyone else here understands and listens to the commentating in Korean but I do.
I usually like it a lot because I learn a lot about volleyball from it, but Han Yumi in particular always praises attackers despite it being due to good receives or sets, and whenever there's a mistake in the attack, she'd comment that the set was not high/good enough for the spiker.
It is very misleading to people who don't know volleyball well enough.
I hope Park Mihee commentates more, her commentating is really insightful.
