An excellent presentation; thank you for making it available to the public.
The picture at the top demonstrates what strikes me as a very strange part of the rules: I cannot think of another sport where they award points outside the competition area, where the safety equipment is no longer useful. If the scoring wrestler has one toe in bounds, the defensive wrester's head can easily be twelve feet out of bounds, and seven feet off the mat itself. I wouldn't like to have to explain to a court that our rules encourage this sort of thing.
