				free blocking zone
			 
			 
			
		
		
		
			
			First year official looking for easy explanation of the free blocking zone.  I know both A and B players have to be within the zone 4 yards latterally each side of the ball and 3 yards deep.  So when does the free blocking zone die?  I know when the ball leaves.   Is the ball considered to have left when the qb gives a basic handoff to the running back.  Because most running backs are 5 yards behind the LOS.  Any clarification would be extremely helpful.
