TR,
This is a position that was developed by Gerry Davis, a MLB umpire. It requires you to stand back a bit further than we are used to. If done correctly it does give you an outstanding view of the plate.
It does require a bit of getting used to. I have adapted this stance to a certain degree. being a bit shorter, I cant set up as deep as the Davis program suggests.
For many coaches and even some umpire evaluators, seeing the stance for the frst time the reaction is that you are too far back to see the whole plate. I have to tell you that it is not so, I get good coverage on the zone.
As to discussing the stance with an umpire during a game, I cant expect you to get too much sympathy. We certainly wouldnt discuss or question coaching decisions or strategies with coaches and cant imagine anyone would meet your comments pleasantly.
I would love to demonstrate it for you some day. I was sceptical at first too.....but I am now a convert.....
