IMO Souths have as much to blame Brett Suttor for as they do Roy Asotasi. After Souths rush to get the scrum packed, Roy pops his head up to look around and disengages from the scrum. It was one of the dumbest plays of the year. The rules have been interpreted this year that you can get time off if you get to the scrum and pack it, but time will be put back on as soon as the other team has formed the scrum or the rushing team either leaves formation or stands up from a scrumming position. Roy was in, then pulls his head out and doesn't stick it back in immediately. It was a schoolboy error and something the captain should take responsibility for.
As far as Suttor goes though, I have no problem with him blowing time back on, but at 9 seconds when it becomes apparent that the ball is 10m downfield on the goal-line, he needs to blow time back off. That's not a South Sydney error. I'm not sure how it got there, did Parramatta throw it away or did the ball balls place the ball incorrectly??? If it's an act of either of Parramatta or the ball boy, then common sense entails that time is off until Wing is able to get the ball to feed the scrum legitimately.
I'd also blame Gavin Badger, it looked to me after the game that he looked a bit sheepish and was going after Suttor to talk to him. As the experienced refereee, when he realised what happened he should have taken control.
