I am being asked how to explain whether slapping the leg with the glove is really necessary or not. I never did it when I pitched growing up and thru high school. I am trying to get an 8U softball team onto the right track in starting proper mechanics and some parents are asking me about this slapping the leg... I watched a lot of the college world series and never noticed them doing it... How can I explain to these parents why some teach it and some don't... I don't want to give them the wrong explanation, nor be teaching the girls the incorrect mechanics.... Can anyone help?
