Tsubaki and the other players try to convince themselves that they're not as bad as they think they are. They're just not playing as well as they used to. They don't know how to play defense, they say, and they can't figure out a way to stop the other team from attacking them. They all start to argue, and the coach tells them to calm down. He tells them that if they start arguing, they'll lose more games, and he'll be fired.
