A violation is called on a player who breaks the rules of basketball defined by in the rulebook for a league. Violations result in possession of the ball for the other team.
In this chapter we will learn about defensive violations.
A very difficult violation to understand and for referees in basketball to call correctly is called blocking. A blocking violation is called on a defensive player who runs into the path of a moving offensive player with the ball and does so before positioning him/herself.
For example, if a defensive player attempts to block or screen a moving offensive player as he/she is moving toward the basket.
REMEMBER: Referees call blocking violations in the moment. It can be very difficult for referees to get it right and sometimes it's debatable. As a fan, you should just expect the variation in this call.
Goaltending is a violation called on defensive players who touch the ball once it is in flight and is moving towards the basket or it has the possibility of entering the net while on the rim.
If a defensive player is called for goaltending the opposing team is awarded the points.
