Okay, I've reworded, re-ordered, and shortened the list. It now reads:
* Do the participants have a good experience with this official working the game?
* Does the official make calls? Do the calls generally seem reasonable?
* Does the official communicate well? Or are players, coaches, table crew, and partners often wondering what just happened?
* Is the official willing to "be the bad guy"? Or does he/she seem to need approval from players, coaches, fans.
* Does the official appear to "handle" things? Or does he/she noticibly defer answering questions, handling situations, making calls to his/her partner?
* Does the official hustle and keep up with the game? Does he/she seem to know where to be? Is he/she often at the other end of the floor from the play?
* Does the official blow the whistle with confidence and appear to use proper signals?
Any other thoughts?
