Setting that aside, I don't think his command of the laws is good enough either. For example, he didn't know that the penalty for a kick-off not making 10m should have been taken from the middle of the half-way line. Even Heremaia knew that and was trying his best to tell him.
I agree he was abysmal when he was last here but in this case he's right and Heremaia is wrong! Its true that if the ball doesn't travel 10m from a kickoff then the penalty is taken from the middle of the halfway line, but the penalty he gave was for a player touching the ball before it had travelled 10 meters. In this case the penalty is taken where the offence occurs.
I remember a case at the Stoop a couple of years ago where we were 2 points up with a minute or two to go. Can't remember the opposition but they tried a short kick off that didn't travel the 10 meters. Unfortunately Karl Pryce "knew" the rules like Mr Heremaia obviously does; picked up the ball; was penalised, and they kicked the penalty (from the spot where Pryce touched the ball) that drew the game!
I have been impressed in the past with George's "laid back" approach. Seemed to work well in the Championship but I think with that style you have to communicate with the players a lot more than he seemed to. You are right about his lack of control - situations escalated because he didn't take firm action in the first place. Still not convinced about the sending off of Scott Moore either; like the judiciary who deemed sending off sufficient!
