Pre-Olympic is rather misleading but ok it is what it is. I'm pretty sure they agreed to be part of that tournament in France since 2 NT members and a former NT member Tashiro are all there so I assume it was already part of a deal way back.
Airi should get cut because she's easily the most useless player. I think Fukudome should stay because the situation with the liberos is still unclear. So maybe Yamada. I like her but Yokota is looking far more aggressive.
im against cutting yamada. they should leave the 2 sisters behind. ameze is too small, hayashi and mayu are small enough as it is they don't need a shorter player that might do so-so and the other is not progressing at all.
