  == Question(s) to develop article ==  Perhaps someone who knows John could ask him a question periodically to help develop this wiki article..  Here is a suggestion for the first quesiton: One question concerns Davis Cup. It seems that John has had a life long relationship with Davis Cup. He coached the USA Team for the Junior Davis Cup for six years, and then in another phase of his life (keep in mind we are talking about a longer span of time then most tennis players) he played for the USA Seniors Davis Cup team. Could you elaborate on your relationship with Davis Cup? What years were you active? and what years where you inactive?
