TwoBits wroteHow did you have enough arms to signal obstruction for each one? Are you an octopus?
Brings up something I've wondered from watching different actions by very experienced guys...
When you see obstruction, what exactly do you say, and how loudly. I've seen everything from a very loud, "I have obstruction at first!!!" to a soft, "Obstruction" to no sound at all --- all of this from guys with more experience than me.
Secondly, how long to you hold up the arm. I see some hold it until the play ends, others hold it until they get to the base they are going to award, others hold it about 2-3 seconds then drop it.
And since I'm asking, I'll say what I tend to do. In a normal speaking voice I say obstruction ... if I'm responsible for multiple runners at the time, I may point at the base where it happened briefly (tell me if this is horrible!), and then hold the left arm out about 2-3 seconds.
