Can she, though? It seems to me that her reception, which could only be described "adequate" on her best day, has steadily declined over the last couple of years. Second Malešević or Blagojević, she is not. One Opp is equally short-sighted, but for different reasons. Surely it would be wise to give Bošković some off games (or at least sets)? Must she play every single set for 10-12 games? Also, Bjelica is to go from a captain earlier in the year to not even make the squad for the more important competition? That's just not how things are done even if Bojana Drča is to take over the captainship. That's not to even mention the fact that while she might not be Bošković, she is still a very good opp, and could be a starter for quite a few teams in the WCH.
If Mihajlovic will make the roster, there's no need for Bjelica. Brankica can easily do double sub for a few rotation (I really don't think it will be so frequent considering how bad second setter is) Bjelica is not terrible but I wouldn't call her good. I don't think she could be starter in any of the European teams playing in WCh
