I agree with most of your comments and yes I wanted my son on the only 06 team with AYSO United to develop because of the Six philosophies. Based on my experience I just want other parents to know the the kids do not come before AYSO United just like other clubs, which was mentioned in an other post and AYSO United will not even discuss it with you, even if you have proof of your kids ability.I understand you are upset with what you believe is a club not following its policies. You have complained a lot about how they are handling the situation and you've even mentioned videoing the games, but what does that help with your kid? Are you trying to get him to stay at the club at that age level? It sounds like the coach doesn't think your son should be on his team, there might be many reasons he feels that way, and perhaps it doesn't even have to do with his skills, and it might not even be right, but it seems clear that's the way he feels. I'm sure you've had a teacher, sometime in your life, that you felt didn't give you the grade you deserved, well it goes the same for coaches....its subjective, might not be right or fair, but it's their opinion!!!
You also mention the worry about playing with bigger kids...If your son is planning on playing in high school hes going to have to get used to playing with bigger kids, most high school teams mix the freshman and sophomores on a frosh/soph team anyway. Not sure if your son in a 7th grader as an 06 but I can tell you that there are 05s that are also 7th graders also he would/could actually be playing with his same grade level. The size of players starts to level a bit as kids get to high school.
Not sure if I agree with you on them not standing by their philosophies. I didn't see anywhere where it stated that if you are on a team you have the right to be on the same team again the next season. I must have missed that part.
Find a new place to play, were the coach believes in your son and wants them on the team. It will do great for you and your son!
As far as the high school is concerned it's totally different, at this age group because of the developmental aspect in the mental and physical ability of the kids they have been divided in their appropriate age group and I did not make that rule, There must have been a study done for that.
On the last part you must have not read my posts before, It is not about winning it is developing the kids which was not followed by AYSO United as they clearly stated.
I used to be a great fan of AYSO United just like you, but now I understand that they are just like any other club and have to find a Coach that likes my kid not my money when his team is falling apart because of the decisions they made in the past, and listen to other parents that the Coach is a terrible communicator, and use us to get to their Goals.
