I'm sure her height played its role. Busato is well know with his height obsession. Yes, we don't have tons of setters like other national teams also don't have tons of setters but there are several options which could be much better than this, Ryseva, Filishtinskaya, Vetrova, Popova, Kondrashova etc. Last year Busato said if they wont take medals in Olympics it will be his problem not players, he said Russia has many good players and many options compared to other countries. Now I have my doubts as if he is a random person not volleyball coach.
But as a sub, she might only come into court during double sub. Then her height won’t matter much. I agree with the previous poster that Romanova might have not recovered yet.
