There are a couple of approaches on how the pre-game should be conducted.
There is the long approach and the short approach. The experience and level of
the game to be played might determine which one can be used.
The long approach. This way of conducting the pre-game involves the
officials going into great detail about numerous variables: what line will be
the out-of-bounds line, what color the line is, basic ground rules and
extraneous information about your officiating style. That type usually takes
more than a minute. While the abundance of information may seem like a good idea
-- especially in a youth game -- players and coaches usually have other things
on their mind than listening to an official's long-winded pre-game. Seek and
answer questions at that time to avoid problems during the game.
The short approach. This type of pre-game is short and to the point.
It lays out the groundwork for the game (good sportsmanship, lots of hustle,
etc.) and leaves the door open for players and coaches to interact with the
officials during the game. It often lasts less than 30 seconds.
Either type of pre-game is acceptable. Choose one that fits your style and
level of the game and use it. A good pre-game is often the foundation to having
a smooth game.
