If you are willing to learn, you can learn. When my DD started playing softball, I knew pretty much nothing. I was a big baseball fan, but baseball was not one of the sports I played. I knew nothing about the details of proper mechanics. I put in the effort to educate myself about hitting, throwing, and the details of being an effective catcher in order to help my DD play at the level she wanted to play. Along the way, I learned about the game, and spent some time coaching my DD's teams.
I'm still educating myself. Constantly. However, my DD won't listen to me, so I pay people to tell her the things I want to say.
I have been at this for over 20 years. When it comes to someones neuromuscular system you can never know enough.
