I wouldn't worry about Goldstein, he's been playing sore/half injured for the past two months after Doggie players shoved a few knees into him going third man up. His form and confidence have suffered as a result, it's one of the reasons why we are pumping games into Daw.
I haven't watched many Kangaroos matched this year, but his stats still seem pretty good for someone playing with injuries. And he normally plays well against us too!
