My time

[rainmaker]

If a player is down, then of course there's not much necessary in the way of a signal, except to beckon the coach in. But if there will be any doubt as to what is happening, I do it this way: whistle, pause until everyone is looking*, pat chest and verbalize "My time." It's totally against the book, or at least it's not in the book, but it's effective and efficient.

*I don't regard this as "drawing attention to myself" or "making it all about me". I see it as good communication.
