It's funny how you comment you know who you are. Sounds like you have it out for one parent in particular when so many have indicated on this thread about bad coaching experiences with Roy. You must be his only friend.
As a dad who played lax in college and goes to both of my kids tourneys, I've never heard anybody yell as loud as he does to pass the ball to his kid then Roy. You are delliousional to think that Roy isn't doing this for free so he can coach his kid.
