All the materials you need to use this program required for youth lacrosse games.
The PDF is Harold Buck's presentation he made at the mandatory rules meeting on March 19. If you have any questions about it, please contact him. The video was produced by USL and NFHS. Those groups are attempting to eliminate contact to the head in lacrosse by redefining the current rules slightly and strongly encouraging more 2 and 3 minute non-releasable personal fouls for contact with and to the head. This doesn't affect slashing, just body checking and cross checking. Although it should be noted that any stick contact with the helmet is a slash in youth play. There is no "just a brush" non-call at these levels.
