I’ll take it SLA you are making wild generalisations rather than attacking me. And I guess you have multiple degrees and letters before and after you name that mean you know it all.
And Cys1 has put it quite nicely, coaching is about being able to transfer complex skills across in an easy digestible format for the learner. Which ultimately the means player doesn’t need to understand that they need to use a proximal to distal kinetic chain to achieve maximum exit velocity. But means if they have a have a stable base and rotate their trunk quickly and extend their arms during the pull shot it will travel off the bat quicker than before.
