What if I know my call is wrong?

[Indianaref]

As others have said, most coaches like honesty instead of a line of BS. Most times when I have admitted to a coach a bad call, usually get a slap on the butt. One thing that helped me early on was when I'm in the lead postion is to center your weight on your heals, it keeps you more patient, which leads to a more patient whistle. A late whistle is always better than a quick one.
