This is a great man down defense to use if you want to pressure the ball. The Rotating Box Man Down Defense, commonly known as Box And One is done with the idea of keeping a defender in front of the ball by rotating towards the ball.
It is a great way to put pressure on the ball and show an offense a look they are not accustomed to. This does leave your team vulnerable to the skip pass placing a lot of responsibility on the back side defensemen. However less experienced teams will have a difficult time recognizing that look.
The basic premise is to get into a box and to rotate towards the pass while locking off the crease and having the defender furthest away from the ball sloughed in.
