at length about throwing. he said you either can or you can’t. he then said his career almost was wrecked because someone told him to change his motion. he eventually went back to what worked and the rest is history. you just don’t easily change a lifetime of muscle memory. leave the kid alone. if he throws a good ball, who gives a shit.
I recall my college baseball coach immediately changing a swing that prompted him to recruit me. i was like wtf...just let let do what I’ve trained my whole life to do. needless to say, I never played again. lol
