Creating overload situations to gain advantage on entries

There is this common misunderstanding of the game, meaning that players should always be spread out on the court. You hear it a lot, coaches yelling to players to always work with spacing and never get too close to eachother.
I struggle generally with people painting themselves into corners, saying things that could limit the way the team plays.
This is a way of doing the opposite. It is a kind of a zone entry, that creates overload situations on certain areas of the course.
