The Sau try is the only major one I can think of. That's cancelled out by the Pomeroy try that shouldn't have been given.
That is where you are wrong.
The Sau try had a pretty big impact on the game, as it put the result beyond doubt. Up until then the Sharks still had a chance.
The Pomeroy try was a square up, after the game was well and truly over.
They may both be worth 6 points to each team, but one team benefited more than the other.
As for the other calls, a forward pass for the Williams no try was spotted, but Buderus thought he was playing Quarterback for the Dallas Cowboys for most of the game, and the refs saw no problem with it.
The double movement call was 50/50, and the Sharks NEVER get those calls.
Having said that, the Knights were there to be put away, and it didn't happen.
