Regarding selections for next week, you'd be tempted to rotate some of the forward pack but i think you have to treat each game like a world cup final. I'd keep changes to a minimum but i wouldn't be too concerned if Cheika started (for example) his bench front row, because we really lose no quality in my opinion.
Obviously if Pocock is 100% fit you have to play him, but i presume he'll be sitting this one out.
Re Folau I'll simply say this - he does seem to be going through a poor patch of form, which i assume is due to him carrying an injury. HOWEVER, even in his current form he's still more dangerous than most players on the field. He was uncharcteristically poor under the high ball but he still got us going forward on numerous occasions. If he's fit, as with Pocock, you play him. But again I suspect he'll need a week on the side line.
