Kelsey played libero because USA didnt have one and they had too many OHs.
Bock as an OH was a disaster. I can understand why she maybe wants to make it happen.... but it shouldnt.
I wouldn't call it a disaster but I agree that she is not a competitive OH at the moment. She is still young so maybe she can develop. Apparently she will play the next season as OH as well (which I don't understand...but in an interview Waibl once said, that she prefers to be an OH). In my eyes she would be an amazing libero in near future but maybe just a mid-level OH...
