If the tactic rely on designated zone of entrapment, wouldn't the opponent eventually discover said zone? Especially a high level opponent who knows such tactic. The way fukuda explained it, it sounds like a tactic that should be done by many teams, not just Esperion. It also doesn't rely too much on wild cards like Ashito, but rather a sense of unity.
I want to see more back and forth, so I hope Vans actually figure something out.
