Do all the top players have personal coaches? I keep hearing about Jasmin Ouschan and her coach Michael Neumann. I'm trying to understand, what can Mr. Neumann show Jasmin to improve her game. I completely understand having a coach/instructor in the beginning. But once your a world class player whats a coach do? If Jasmin misses a shot, she's got the video tapes she can review and see what happened. Or is a coach to the pro's more of a motivational supporter?
