Overtime

According to John Hill (during a recent clinic in Texas)
exactly one official signals GOAL -- the lead. Watching
the goal line and crease is the sole responsibility of the lead. The other officials watch everything else. Thus
there is little reason for the lead to miss a score unless
they (the lead) are terribly out of position.
Also, if anyone else is going to make that call, they must
be in an acceptable position.

When making the signal, charge the goal as they sound the whistle and raise one hand. They then stop at the edge of the crease and raise the second hand to signal the score. Do not run with both hands raised. Whatever you do, don't signal a goal flat footed from outside the box or the top of the box. You will have a hard time selling this call -- especially in upper division play.

It takes 2 to 3 seconds for folks to find you on the field
when a whistle sounds. Make the habit of hand up + whistle to make yourself easier to find. Flags, signals, other announcements can follow the hand+whistle because folks have found you on the field and are watching whatever you do next. [It also gives you a couple of seconds to clarify in your mind whatever you are going to say/do next.]
