Mike...I understand what you are saying to an extent, but also have to disagree for some kids and/or positions. Being in the same team with you and your daughter, I agree that you don't need to spend money for these things. Your daughter is very successful, a hard worker and we are fortunate that we DO have a coach with a lot of knowledge, his own setup, and the commitment to his team/girls to work with them pretty much whenever we want/need. We also have the advantage of frequent assistance at a high level for the fielding techniques during practices. Not every player has these advantages or has a parent with the knowledge to teach these things. Not every coach has their own setup up, either. Often rental prices are required.
Also, when we start talking specialty positions like pitcher or catcher, I believe it's very important to have high quality, regular instruction. My daughter goes to her instructor regularly. Now that she has her basics, he picks up small things/errors quickly when they can be corrected easily before they become hard to break habits. It is invaluable and I believe it helps not only her, but also our whole team. Granted, I don't pay anywhere close to $100/hr even though he is, in my opinion, one of the best in Ohio and worth every penny I do pay him. As good as our head coach is, I don't think he could provide the experience and knowledge specific to catching that Amber receives from Bill.
