How to use your whistle?

[btaylor64]

I am very glad I have asked this question and thank all of you for the replies. I use my whistle as another "tool of the trade" or tool to help me express different plays and different situations. I personally feel it can help you emphasize a play of more importance, or when there is a double whistle and I know that I want to take the play. I have yet to go to a camp where, what I call utilizing my whistle, has been brought to my attention, but it is very helpful to know. Thanks.

P.S. I use a longer blast for my time-out as well.
