Is the break going to be beneficial for them or detrimental?
I'm thinking the latter; there's nothing like playing the matches & maintaining match fitness, to keep you on top of your game.
7. Hooper (c)
13. JOC (James O'Connor)
16. Uelese 17. Slipper 18. Tupou 19. Coleman 20. Pocock 21. Genia 22. To'omua 23. Petaia
There are so many potential selection options in the backrow:
6. LSL (Lukhan Salakaia-Loto) 7. Hooper 8. Naisarani
6. Demspey 7. Hooper 8. Pocock
6. Pocock 7. Hooper 8 Dempsey
6. Pocock 7. Hooper 8. Naisarani
Dempsey has definitely improved his chances in the last couple of weeks and Naisarani has worsened his. LSL (Lukhan Salakaia-Loto) probably also did his chances some damage with his yellow card against Uruguay.
On the backrow, I see you have predictably shown Hooper as the only No 7 option. Again I think you are right in Cheika's brain (do you find a lot of empty space there?) but to anyone else, Pocock is also a No 7 option. I will never get to see it happen with potentially only three more games until Pocock retires, but I'd prefer Dempsey, Pocock, Naisarani as the starting backrow, especially against England (and SA and NZ).
If we had a kicking 5/8 I'd be happy for us to just play 10 man rugby and pin the bastards in their 22, but we don't so we'll resort to one-off runners being battered by the English defensive wall.
Good luck to us, but I'm expecting a bit of a pantsing.
