I just re-watched the JPN/RA match and it wasn't as bad as it felt like live. Don't know why Momii didn't mix it up as much as last week, but it was NOT because of bad reception. Japan made more reception errors than ya like but those don't even get to Momii. The vast majority that made it to her were excellent. She barely moved.
It is true (and troubling) that Ai and Mayu are not Yuki and Risa in floor defense. But give it to Brazil. They hit hard and found holes.
Highlight for me was Sarina's Yuki Nishikawa-esque flat-footed walk back to the huddles after making a kill She seems to be taking this more seriously than others. But that's her style.
As an aside: I wish Coach Lovebunny would teach Kurogo how to make kills from zone 3. That's a missing ingredient for me
