BH, I have evidently misread your post, but looking at it (above) I really don't see any mention of injury cover, although the link might be back to the earlier comment that you were replying to.
I have no argument about moving players to cover injury at the back end of a game, but even in that situation I personally would be loath to move Maddocks when a player like Newsome is available and who can play both 13 and wing. But circumstances at the time would dictate.
Like others here, I don't understand why Moeroa seems to be out of favour.
In relation to the Brumbies, and postulating an injury to Ikitau at 13, I would guess Simone would move to 13, and someone like Pasitoa or Kuenzle would fill in at 12, probably in the short term and maybe even longer. The alternative would be Tapine to come in, but he is very inexperienced at this level, or sensibly Kata when he is fit again.
I wonder if many of the SS followers here know that Simone played occasional games at 13 for Northern Suburbs?
Maybe when Donaldson returns Moeroa can get a run on the bench. Donaldson covers 10/15, Maddocks can shift to the wing and Walton/Newsome covers 13.
We've currently got Edmed on the bench covering 10/12 and Nawaqanitawase covering the back 3. Newsome covers 13.
Our backline for this match is:
9. Gordon 10. Harrison 11. Ramm 12. Walton 13. Perese 14. Newsome 15. Maddocks
21. Grant 22. Edmed 23. Nawaqanitawase.
My post was about how you could include Moeroa on the bench and I suggested that it could be 22. Moeroa 23. Donaldson. This is assuming the same starting backline.
In our team to play the Reds, Edmed covers 10/12, Nawaqanitawase covers the back three although I would guess he will always play wing and Newsome would move to fullback. Newsome or Walton would cover 13 depending on whether you had already made a sub.
In the situation where Moeroa comes onto the bench and he is essentially just a 12 and Donaldson is a 10/15, you need someone else to cover a couple of positions. Newsome or Walton would still cover 13 and someone has to cover wing because it wouldn't be Donaldson playing there. My take in that team is that Maddocks would be the obvious one to shift to wing if one of your wings got injured.
I guess you could bring Moeroa on to 12, shift Walton to 13 and Perese to the wing but that is a lot more disruption.
Clearly Newsome can't be the wing cover when he is already playing there.
That is my point entirely regarding the Brumbies. The back reserves don't cover every position in the backline and in this situation, the 13 jersey would be filled by someone already on the field (Simone).
