Please comment as inclined.

"The reason for mechanics, whether with the two- or three-person system, is so that you are:
...in the right place,
...at the right time,
...observing the right thing,
in order to
...make the right call (which might be a no-call)"

Your seasoned thoughts and critique is appreciated in advance.

Is something missing? I can't see anything here remotely controversial. All this seems to say to me is that we need to use designated mechanics to cover the game properly.
