Yes, with lower ranked players and earlier in the draw, this will win him matches more easily. But as he advances and runs into better players with better returning skills, the serve will not hold him well any more. His game seems to be very demanding on the body, and as it wears and tears more, he will have a harder time (it seems to me) in best of 5's, in the second week. This is why it was very encouraging to see him try incorporate S/V more.
