Last time they had two top level MB, Thaisa and Adams, it didn't work well for them. So I think it made sense not to fill the roster with so many star foreigners unless there's an injury such as Beyza's
adams was crap as gibby is in a block this year and thaisa was injured most of her contract and they had kosheeleva with her awful reception it seems ecz just cant get a compact team together reason vakifabnk is so successful is they have the best compact team in the world and even when zhu is injured they can still win sets and games
