There is this really popular girl on my volleyball team and I am the team captain and she always refutes what I say and never listens to what coach says but she is a good player. When she gets pissed, she doesn't talk to anyone and when coach is talking, she ignores her and laughs at other players. As the team captain I should be able to handle this but I have tried to talk to her about it and two coaches have called her out on it, but she still won't stop. Advice?
