I did not see this til now. I wish him the best of luck. The only advice i could give was tell him if he doesnt make the team thats fine not all kids do but next year if he trys out again and the coach know he gave up before tryouts where over last year he might look him over if it was between two kids the same. I would not push him say your peace and let it go, end the end it has to be his choice, just tell him dont forget your glasses if you try out... best of luck to your son!!
