From my pregame:
Lead’s Primary Responsibilities: Primary coverage area. Post play. Illegal screens at elbows
Trail’s Primary Responsibilities: Primary coverage area “works the arc”. Rebound coverage.
Drives starting in primary. Last second shot, basket interference, goaltending. Bring subs in
Stay in your primary, it must be obvious to come out of your primary. Seldom should have four eyes on the ball. If something is there that needs to be called, call it. We’re not going to have too many double whistles if we are doing this right.
