I have been in both places, on the mat and in the stands. I am a certified coach, but always a mother, who had sense enough to know that my child knew more then me and that someone would be a better coach for him. I still help with the novice kids when needed. But as a parent in the stands, another problem to address other then parents at matside it is coaches. When 2 or more coaches stand together at mat side their is people in the stands that can't see. The best I have seen for seeing from the stands and getting parents to stay there is Holtons sub-district last year with the warm up area on the sides not in front of the stands. I agree something needs to be done, but no one will come up with the perfect solution, but keep trying.
