Lol knetz, the setter all short of course they need double sub to keep blocking line high.
i think the real problem is their defence is so weak, often time they just stare at the ball.
like KYK said this a totally new team, they lost 5 starter, this kind of result should be expected.
isnt this a perfect wake up call to korean volleyball, this is the reality right now, if there is no change gonna happen, they probably wont be competitive in world volleyball
