Man, this really hurts to give credit to a Marine, but I have to give credit where credit is due and say that the most talented active duty player I have ever met over my 20 year career starting in 1990 was a Marine named Ray Roberts. I met him in 1997 in San Diego and he won the National All Military Tournament, man he could play.
As a group if it was like a Mosconi style event, I really think the Navy would prevail.
Could that have been Robert Ray instead? There is a Robert Ray who I think was a Marine who now owns a pool room in North Carolina. This Robert Ray plays pretty sporty and did well at the US Open one year if I remember right.
