"That said, don't expect the same from the teams. From what I saw for over ten years, there is no 'proper etiquette' with other coaches pursuing kids. There are some fine coaches/ organizations but alot are not. Make sure the team you are moving to is being upfront with your son. As many as not, will promise playing time and recruit right over your son next tournament." --Prep Ball
Prep Ball has it right. These teams are money-making businesses. Never think that there is a true commitment or any loyalty--other than to the kid who, in that moment, means a better profit. I have watched many, many great kids get stepped on by many of the teams folks in these parts think are the premier club teams. They even use the kid and his image to promote themselves, then when Buzz Lightyear comes along, they throw Woody to the wolves.
Sure, that sounds cynical, but in dealing with Club sports (not just baseball, mind you) for 15 years, I have learned the bottom line--profit. There are used car salesmen with more integrity than many Club managers.
Finally, I suspect that there are one or two decent folk out there in the business. I just have not come across one yet.
