Yes, the point I was trying to make was someone doesn’t have to be physically gifted enough as an athlete to train someone else to be a better player.
you can teach technique, mechanics, motion, a swing, a delivery etc etc. you can’t teach 6’3” you can’t teach being born with a ton of fast twitch muscle fibers.
you obviously can’t be a stiff, but some Of the best coaches in all sports have personally had very pedestrian careers as athletes themselves. I do think playing is paramount, and knowing your craft, but not having the stuff to play at the highest level is in no way an indictment on someone’s ability to teach.
