Change to Restraining Line Rule-
The ball will not be deemed in play until after a defending player receives or touches the ball once it is released from the goalkeepers hands or from a goal kick.
THIS IS A CHANGE TO AN EARLIER VERSION THAT SAID ONCE BALL IS RELEASED VIA HANDS OR GOAL KICK THAT THE BALL WAS IMMEDIATELY IN PLAY.

Even though it is geared as a speech about youth hockey, the principals are still so good and apply to any youth sport. It is 9 minutes but worth the listen.
Give the game back to the kids !
