Wings probably depend on how concrete those two were to begin with, but both were threatening but uneven with errors and rust in their games that leave an opening for someone else to come in. I'm not sure that the Potter/Jorgenson pairing is the most balanced either, I'd probably be looking at one of Pietsch or Daugunu to come in.
In the props I suspect Bell will start, though that will just be a straight swap for Slipper. Not sure about tight head, Nonggorr didn't do anything much wrong but didn't stake a claim. Tupou didn't really impress on Saturday night, but the fact that he was not called into the AU/NZ side suggests they might want him back into the 23.
