			I always verbalize my calls and explanations. This (usually) alleviates the need for explaining to the non-deciding players and coaches again after giving the signals. 
 
Also, as Warrenkicker stated but also at a lot of our varisty games, the crowds are generally so small that I can let everyone know what's happening. Sadly to say, turnout for football games at all in this region (NE North Dakota / NW Minnesota) is sketchy at best.
