One thing that I don't think is emphasized enough is the importance of the serve toss's depth into the court. I think, too often, recreational players toss the ball too much straight up and not enough into the court, resulting in a weaker serve that lacks the power of the body's forward momentum into the serve. This is what results in the server ending up inside the court instead of staying planted behind the baseline. I think once this toss into the court depth riddle is solved for the server, the matter of clock placement (11 o'clock, 12 o'clock, 1 o'clock, etc) is easier to determine because the overall "feel' of how the serve should be hit is much more correct. Thoughts? Opinions?
