I don't know if it's just me, but lately I've been noticing that in about 90% of juniors their serving motion or pre-serve routine is just ridiculously complex, jerky, and utterly pointless. It seems as if they are either trying to imitate some random pro, usually Roddick or Nadal, or it is simply to look cool and has no real purpose there. I've encountered dozens of kids who bounce the ball ten times against their racquet ten times, do some weird motion with their feet and racquet, then bounce the ball with their hand a few more times, then when they finally serve their form is way off and it goes straight into the net. I understand that many kids out there want to look like the pros with their serve, but most of them don't understand that the pre-serve routine is actually supposed to do something for the server, not just look cool. It may just be that the answer is something as simple as, "They're just kids" but I have no idea why no coach decides to tell their student to make their motion simple and just hit the ball. So why is it that no junior tries to emulate the serve of someone like Sampras or Monfils, who both have very simple and to-the-point service motions?
