on a couple of my assessments this year both assessors have advised me to brief both CAR's together and with the captains, although i'm not expecting to much from them, i'll very very briefly explain that i dont want them flagging for some one just stood offside, and explain if they can wait as long as possible to raise there flag to wait and see if that person receives the ball. Make a little joke about how frustrating it is to see your own team member running past that person offside only for the flag to go up. Trust me this lasts no more than 30 seconds to explain, but i make sure the captains hear this so when they are delaying there flag they aren't getting abused by there own team, as the captains have heard my instructions.
It's not 100% fool proof, but i do genuinely see better decisions and less dissent from teams over offsides, of course you still get the odd one or two who will stick the flag up regardless.
I always say to both CAR's "if anyone gives you any shi*, just let me know" (makes them feel like they have my backing all the way)
Try it, if it doesn't work, try something else.
with regards to capt's i don't go in to much, explain i try and let the game flow with advantage, so please give me a few seconds before shouting at me. We all know teams have that one person who will go over the top with the abuse, please speak with them before i do.
Thanks lads, have a good game.
You'll find something that works for most teams, but sometimes what ever you say, it'll be like you've just spoken Japanese to them as they'll ignore every word.
My club marks are through the roof this season, so something is obviously working.
