@Work=wins Ted isn't getting the barrel flat(or nearly flat) before he launchesDbsf is a one legged issue. Not this young ladies issue. She has a pulling core. No need to keep the barrel vertical. She isn’t leveraging her back leg.. Get the shift of mass consistently on time.
Ted had DBSF? No he did not. He had a pulling core. There really is no such thing as Dbsf. Well to one leggers Dbsf is a real problem.
When one can leverage the middle. The barrel or back leg isn’t needed for leverage.
trying to hit a ball well when the pitch is below your belt is very difficult (among other problems) when you launch from that position..believe me..
Edit: I do agree with you regarding her getting "stuck on her back side"
