For our driver + operator, we do a good deal of driver practice to get them in sync and recognize what to do with certain key words--however, we still use a third person as a coach, since it makes it much easier to A) communicate with other teams without setting our eyes away from the field and B) to notice things we don't see. It really helps when the coach tells us the big picture, makes it a lot easier to avoid making terrible mistakes.
