As far as facility its indoor and its probably one of the better ones. But all indoor is horrible.
Sports science did a show on being a UMP. It was very well done. They put the host of the show in the position, as best they could, to simulate the pressure behind the plate. Even in a controlled environment that test subject could only get balls/strikes right 75% of the time. I think as a player/coach you have to do everything you can to take the ump out of the game. I am not advocating on a ump running amuck, but how many times do you hear complaints about balls/strikes at the field? Teach the kids to adjust to the zone and take away the excuse. Just a thought. I am not saying a bad zone is ok, just not worth arguing about.
Rules- there is always some nuances between sanctions/facility. Unless it cost a game for someone?
