Best ways to find time for coaches

[Nevadaref]

Don't worry too much about talking with the coaches. When a coach truly needs an answer, he will find a way to get it. The official doesn't have to worry about making it over to the coach. The opportunity will eventually present itself when warranted.
In fact, it is often better to give no response at all to some of the things that coaches get upset about and just move on with the game. A coach will have perhaps one or two legitimate questions during a game. Anything more is just bellyaching and needless complaining.
