Coaches who act out are an embarassment and send the wrong message to kids, modeling that their behaviour is how an adult acts when they don't get their way. They encourage players and parents/fans to also mistreat officials. And they can cast a negative light on the rest of us coaches who don't behave like @sses just becasue we didn't like the call.
So I am all for it, and I hope it spreads to other States. I'd take it a step further- I think it should be a part of the mandatory coach certification if a State has this. CA does. Maybe nip some of this BS in the begining.
