Studying for my HS officiating test; reading each page of the NFHS 2024 Boys rule book.
One rule that I was completely wrong with and I believe nearly everyone will be shocked is:

Rule 4, section 8 (page 41)

Goalie, or any player in possession of the ball (while in the crease); a) brings the crosse back through the plane of the goal, or b) brings the crosse back through the plane of the goal and the ball drops to the ground across the goal line

NO GOAL.

It's a little mind blowing that this is not a goal.
