[Back In The Saddle]

Using the whistle gives you one additional tool in your box. When a coach is getting near the line, and won't back off by talking to him, then it can sometimes be helpful to put the whistle into your mouth. It serves as a warning that the T is imminent. I've had it work before.

Just to add a thought to blindzebra's comments, sometimes it's better to hit the whistle, signal the T, and go find your partner immediately. Take 30 seconds to talk about what you're going to do next, who will tell the coach to sit, which end to shoot FTs at. Then go back and report. It gives the coach a few seconds to calm down. And, if he's still going strong when you go to report, you have ample justification to unload him.
