Does the HS head coach have any interaction with the summer team at all? Does your son communicate with him? Your summer ball sounds exactly like ours did, which is why my son never played. Coach unqualified to coach, or at least unqualified to deal with kids on his own, lack of instruction, etc, etc, etc. I can name 3 teams where my son would have at least considered playing summer ball if he attended that school....only 3. The others are just glorified rec ball in most cases. My suggestion, maybe have your son communicate with the HS coach and then look for a different team for next summer as tryouts for 2018 are happening now.
