I can only mention things I've seen, but this is an even more extreme example of a referee not having the knowledge needed to do the job. Again, occasional errors in observation or judgment are pardonable, but errors that are caused by referees lacking the knowledge to make the calls are not.
Why are referees that lack the core knowledge to do the job being certified by WPA? Why does it seem that referees getting the most noteworthy assignments in pool are the ones making the most errors? Why doesn't WPA care about the precipitous decline in performance of referees in pool?
I think referees have improved at crowd control and in keeping the proceedings smooth. I also think they conduct themselves admirably on a regular basis. In these respects, we have a really good crop of referees in our game. If we can only fill in the gaping holes in their knowledge, they will be the best referees in the history of pro pool. Unfortunately, there is no tangible evidence that filling in these holes has priority with either governing bodies or event producers so, until this changes, it's hard to expect better.
