Judging is a tough thing to do, and I applaud Jon Greeson giving up his very good chance at making top cut himself to judge on Friday.
I also am thankful for John Earley giving up his very good chance at placing in TEAMS to judge during Nats. There was a time in a game where my team was playing another top team, and a mistake was made that none of us caught. John Earley happened to be passing by at the time and saw what happened and corrected the mistake. This was entirely the right thing to do. If a judge sees something happen wrong, then they are entirely within their rights to correct it.
I'm not sure if that's what Justin is referring to about playing enhancements, but just in case I thought I'd mention it.
