Whatever it is, this is a big chance for Kreklow to step up and make her mark. Unfortunately, I am not sure if Lloyd is a good fit, despite how talented I think she is.
I would guess that even with Glass out, Thompson will remain the setter only for inversions. As a USA fan, I would not feel comfortable with her as a starting setter in an important match, she would get shredded on the block by a top outside like Kosheleva or Zhu Ting.
I know Japan was able to succeed with a short setter like Takeshita, and Italy with Lo Bianco, but we are a different team and what works for them would not work for us.
