Final chapter. I emailed the board. Made it strictly about my sons lack of expeirence and not having fun. I did speak the other coach prior, but made it only about my son. Apparently the other team needed players and he likes my son having coached him last year. Got an email today that even though this is not typical protocol they granted our request, considering other circumstance, and this may not happen in the future.
My son is happy his new coach reached out immediately to welcome us and talked to him. We didnt have to go through a team manager. He starts practice tomorrow.
THANKS FOR YOUR SUPPORT.
