Mid-Season Note

Officials:  Youth leagues have just begun, college is near complete, and mid-season is upon us in high school.  Just as teams are making adjustments to excel, so must we.  As you know, we are judged on five general categories by coaches:  rules knowledge, judgment, hustle and positioning, control of the game, and uniform / appearance.  Based on feedback received so far, there are a lot of good looking referees out there and this good first impression helps us all.

Here are a few items to keep in mind as we enter the second half of the season.  Remember, these are all based on the assumption that you know the rules:

  1. The game requires consistency on our calls throughout a game both as individual referees and across the entire crew.  Whether it is face-offs, loose ball holds and pushes, or situations with heavy contact, we must to be in position to see the play, adjudicate it correctly, and consistently.

  2. The game requires communication.  As we make – or do not make – calls on the field, we generate questions and inquiries from the sidelines and the players.  We do need to respond to reasonable inquiries and may have to agree to disagree in the end.  However, we should not pass on opportunities to appropriately engage with other participants.  After all, we may learn something based on a coach or player’s perspective that will benefit us in the long run.

  3. We must be the consummate professionals even in situations where others lose their cool.  Lacrosse is a fun, passionate, fast-paced game and the officials are there to maintain safety and order.  Whether we do this with a calm demeanor, a reasonable voice, and/or our penalty flag, we must not lose our cool nor give up on our role as the game manager.

I hope the rest of your lacrosse season is enjoyable and successful!  If I can be of any service, please do not hesitate to contact me.
