This swing is SO close to right....that the nonsense purveyors have to talk about ridiculous surface details like front hip action....so they can look like they know something.

You can't really have a top quality lower body....without a top quality upper body....and vice versa. There is just ONE thing that goes on....and it involves the upper working against the lower....and the lower working against the upper....to create that ONE MOVE swing. So one can not be good without the other.

However.....what she is doing with her lower body is EXCELLENT. And a proper barrel turn, from the proper spot, will send her to her potential. Any surface lower body flaws go away with the proper upper body action.
