One simple step that could be taken is to put two chairs in each corner. At least then as an official I could ask the coaches to please sit in the chair. And maybe the presence of chairs would limit the number of people on the mat. It is frustrating but almost impossible to control. You would never get anything accomplished but clearing mats. With that said I was impressed with the attitudes of the HS kids that wrestled and their aggressiveness the majority of the matches. The majority of the coaches were also awesome to work with. I really enjoyed officiating last weekend.
