Most coaches teach the CF to get anything the can. If the CF calls the ball it's her ball period. In your situation did the RF call for the ball? If she did, the CF should have not called it, but once she did the RF needs to peel off. If she didn't call it I can't blame the CF at all for calling it. As the kids get bigger the field shrinks so some can cover a lot of ground. The big issue as a team is that you need to trust that if you call and have priority on the ball that you trust that the others will let you go for it.
