I thought their current coach was supposed to be an upgrade when Asako Tajimi split for Hitachi a couple few years ago. I looked at his resume experience but don't know anything about him. He's been coaching around for more than 25 years
He's not doing anything for that team they're stuck in a rut regardless of them wanting to improve this and that it's not happening with his (lack of) strategy.
They should call that charismatic NEC coach you posted before. They need to convene on getting someone who will propose a different system, and understands their players strengths and weaknesses. They don't have any good pairs/combinations.
