I have a question on those serve instructions. This proverbial 'diaper holding' server analogy discussed here:
is essentially very similar to the practice tip described here:
which is all great, seems like a useful practice tip.
what I'm confused about is that in the Jeff's video, he talks about and demonstrates how the racket face hitting the ball ends up facing the player (see at 3:23).
While the McCraw's instructions seem to suggest that the face of the racket hitting the ball ends up facing away from the player (see at 0:29 mark)
So,which is it? Is one overpronating more than the other?
