Not a surprise. Rapid had designs on a championship to celebrate its 100th year. For whatever reason, it doesn't look possible with the players selected by the coach. Weaknesses at OH and reception, as others have pointed out. So the coach had to go . . . Rapid can't fire all the players. I expect even more changes . . .
Their biggest weakness is definitely in the receives of their 2nd OH (which rotates between 2 Romanian players)
Simply targeting them will cause the team to crumble
So far their setter Lee Dayeong who's agile and tall has been mostly able to save the poor receives and convert them into decent to good sets (also during her time in PAOK), but when she sat out due to her hamstring injury for Rapid's match against Voluntari, they collapsed badly and lost 0-3
Rapid has a fairly inconsistent Romanian OPP
Also Jennifer Cross's blocks has been good but her attacks seem off, her jump feels very slow and heavy, so she's not scoring much at all
Now that they've recruited a new foreigner OH Sara Klisura, and with the 4 foreigner limit in Romania, I have a feeling Cross will be the first foreigner off the roster
But this will mean a Romanian MB will play, and Pusic's time as a libero on court will be halved since previously she swapped with both foreign MB players.
