Oh, I understand your position a little better.
Even the term "drop" could confuse someone who thinks they need to force the racket into that position.
When I'm teaching, I use the term "lag." I tell my students to relax enough to allow the hand and racket to lag. I do see some beginners try to force the racket down into the drop.
This is when LeeD's talk about throwing comes into play. Someone who throws a ball well allows the arm to externally rotate from the shoulder and let the hand lag. They are not trying to force the external rotation but allow it to happen as the body and elbow drive forward.
Allowing it to happen makes a big difference. This is why some of the biggest serves I've ever hit seem relatively "relaxed" in terms of muscular tension.
