I can pretty much hit a great overhead when i take it on the bounce and i can get behind the ball and move into it. The overheads I have troubles with are the ones where the ball gets behind your head and if you were to hit it normally it would just go out. Usually happens on good lobs that have a good horizontal component to them. When you try to hit it in the air in front of you it would be too high, but if it were over/behind your head it would be perfect height. How do you handle these overheads when you don't have any time to move behind it? I read in a previous thread about a windmill motion? Any explanations of this or help otherwise would be great.
