This is an example of a blocking foul. A defensive player must establish an initial legal guarding position without causing contact directly in the path of the offensive player. In this example, White 7 arrives late and never establishes an initial legal guarding position as Black 11 starts his drive to the basket. Black 11 continues his move as White 7 tries to play catch up defence. White 7 never gains legal guarding position and makes illegal body contact with Black 11. This is a blocking foul by White 7.
