Every parent needs to read this book if you have kids in sports. As a travel baseball coach myself I try to explain to parents our main concern is the health of their child. I have seen over the years other teams pitching a 12 year old 80 pitches and than same kid play SS the second game of a doubleheader. Seen kids at 16 years old throw over 90 pitches and play SS next game. Parents have come to me after a double header and ask why their kid did not play 3rd base after pitching the First game pitching and throwing over 80 pitches ? My answer was he pitched a great game and his pitch count was 80 pitches so we DH him the second game but rest his arm and not play the field so his arm gets rested. His dad said oh he was fine and no reason he should have sat! My reply was why would you as a parent want to over use and take a chance to hurt his arm like so many parents do? Also told him if they are upset than they should look for another team to play on because no good coach would agree with him and if they did agree they should not be coaching. I was so happy when this book came out from one of the top great Doctors of all of sports Dr Andrews. I now tell every parent to read this book because if I can help just one kid prevent hurting his arm than I'm happy. Bottom line is there is a term of over training! Thank you Dr Andrews for writing this excellent book, Tony C.
