Are you looking for your son to be recruited, or just play at a higher level and improve his skills?

If you are looking for your son to improve his skills, you need to know the credentials of the "A" coach and weigh that against any alternatives your son may have.

If you are looking for your son to get recruited, you need to find out what tournaments the team will play in. For the most part, the level of tournaments an "A" team is entered into will not attract many college coaches.
