100% agree with you, and I use the comparison to throwing as well. The forward/uncoil is my biggest challenge right now with all of my younger kids.Yes, basically. The idea, whether you believe that separation happens naturally or is a actual action that is purposely done, which I don't want to debate, is that young players at least imo do not know or understand when in sequence this is to occure, timing wise. I will just say IMO it does not occure naturally for youth players. It has to be taught. One way I have found to get the idea across to tell her to think of throwing a ball. You separate on the forward move. For some reason when it comes to hitting it doesn't translate in their mind very well.
90% of youth players understanding of the swing is ALL BACK/COIL and ALL FORWARD/UNCOIL. This is from me viewing players generally 12u and under
