overlapping position help

[SDUMP]

The more you work, the easier it will get.

As far as the server, there are no overlapping restrictions on her or the CB, since the server is outside the court. After saying that, the other five have to stay in alignment, but that isn't normally a problem because they will position themselves as close to the position they will play during the point as they can.
All restrictions end on contact of the serve. You will notice the setter hiding behind a passer and running to the right front on service contact. There are really no restrictions during the point, just that back row players can't attack in front of the 10-foot line or participate in a block.
At the high school level in SD, overlapping does occur but normally it isn't intentional - trying to gain an advantage - it sometimes is just as confusing to the girls as it is to the officials.
