Most misunderstood rule

[coachgrd]

A little poll here...

What in your professional opinions is the most misunderstood rule by coaches? I know there are several coaches who read this board (and some ever have the guts to post!) and we might be able to come to a better understanding with your help.

I've read the board and have picked up a great deal myself through your discussions!

Thanks and have a good day,
