I wonder who the referees truly answer to? Themselves, the RFU, ... ?
They don't seem to answer to the players or the fans.
And in that, lies the issue. They are unaccountable. On the pitch, that is how it should be. But a bad job at work should lead to pathways to improvement (not punishment or criticism, it is a hard job for one person to do).
If ever the Prem clubs break away from the RFU (and, frankly, there is no way they could do a worse job than the RFU are currently doing), I think the first change should be that the games have three referees, and not one referee and two 'assistants' (sorry, make that silent inflatable water bags that wheel up and down the touch line).
Most of us are ex players. We know the pain of inconsistent application of the 'law'. It is more than irksome.
