Listening to the miked up referees in the 6 Nations Rugby Union makes you long for a similar situation in football.
The authorities had the option of being open mike when the PGMOB decided that voice contact between officials on and off the pitch was a necessity for adequate match control. Unfortunately, they chose secrecy.
Many dubious decisions would achieve greater clarity with either verbal explanations or unintended referee vocal output. And I guess that this latter aspect is the reason that we will never hear what Graham Poll has got to say about his choice of decision.
Shame...
