There are a few problems, but wrestling on the edge is the one that needs to be fixed first and we've been trying for years.
First they extended the out of bounds, but guys just got better at wrestling there. Then we put in an overly complicated way to call stalling and initially it looked like it was going to help, but refs now call continuous action no matter what and never call fleeing the mat so its probably been a net negative. What next? It would seem to be a push out.
If we dont figure out something guys will continue to wrestle with their butt just inside of the out of bounds line while sitting on a lead. Right now the edge is the safest place on the mat and it needs to change.
