This is a defensive play against a dominant centre. Players drop off people to get the ball to the 5 then foul hard and drop back. For this play to work, the rest of the defenders must press their man and stay in the lanes. The point is to get the ball stuck where he cant shoot and has to pass it, hopefully resulting in a steal. If the x5 is slow, this will not work. the ball will be able to be passed into their centre and he will score.
