I wish you could see the kids the coach kept. You would understand. I am done with this forum. Good luck to you all.
KTC, when I first landed on this site ten or so years ago, I received some direct messages similar to what I tried to give to you. I didn't like it - got butt hurt, pretty sure I almost bailed on the place. Then, I realized the messages had enough truth in them for me to learn something and I hung around. It has been very beneficial to me, my kids and the many student athletes I have coached since. Hopefully, you can hang around and find some of the same.
So, even if a few of the kids were lesser players than your son, I encourage you to see the big picture.
