Because they didn't play any of these tournaments with their A-team except for maybe 1 whole VNL tournament
And yes I'm gonna bring up ECH, because it's a though competition and they won it twice pretty clearly!
As you just pointed out that Serbia was hiding their A-team for nearly the whole cycle, how could they dominant it then?
ECH was tough just because there’re many teams at similar level, but none other than Serbia reached the semis here in Tokyo.
