They are human & make mistakes. Unfortunately a refs mistake on mat 11 could have caused a kid to sustain an injury that might have been avoided had he been watching the match. The kids arm/shoulder was wrenched in a direction, well beyond the normal range of motion as we all watched and yelled for the ref to take notice before damage was done. I thought one of the reason for having a ref was to keep the kids wrestling safe. We observed many mistakes such as this one and others on mat 11. The competition was great and well ran but I agree that if you are holding a tourney of this quality, you need the best refs!
