Back elbow is outracing the hands, she's dragging the bat. I also feel she could do a little better job of maintaining posture, her body does stand a little taller at launch.
I know this is not an absolute in hitting, but maybe at heel plant if her back elbow was parallel with the ground (back shoulder height) it would help with the bat drag. JMHO
In regard to posture, nobody explains better then this guy IMO
She looks very athletic though, meaning she can probably get a way with it to some extent.
This guys a complete clown and fraud. He can't even set up his cage properly. Shes hanging up on every swing and does nothing about it. Shes planting a bug with every swing
