I'm guessing getting those girls to do what you coach them to do doesn't always work. It works a lot better at the NFL level but there isn't a coach in history whose ever gotten their players to always do what they've coached them to do. People are people. Guys (and girls) make mistakes and/or fail to execute no matter how perfect the coaching is. Obviously not all coaches are created equal, but blaming the coach when teams lose is usually misguided. Not always - but usually.
