The good thing for everyone else is that the journey the Tahs have been on can be condensed down into two elements:
Forwards with aggression and physicality
Backs with skills and running
Any player who has seen that happen in NSW can make that their foundation for getting themselves noticed.
Pfitzy, this is precisely the game plan I would hope to see the Wallabies play as well. I think most of us recognise the importance of the forwards providing front foot ball and for the backs to run the ball with skill and determination rather than engaging in a kickfest.
But atm there are only two Tahs forwards in the starting pack and potentially only TPN and Palu to come back in. Of those two, it is probably odds on that one will be on the sidelines with injury at any one time, but in any case TPN is probably on the bench behind Moore (just my presumption). Will the Wallabies' forward pack be capable of replicating the aggression shown by the Tahs' pack in the Super comp? Are there any other up and coming forwards coming through the Tahs' system who will demand selection? Or, was a large part of the Tahs' success built on the role Potgeiter played? Is Will Skelton the saviour of the Cheika game plan? Will he be able to dominate in the open to compensate for his other short comings?
The Tahs had the players to implement this game plan at Super level, but it is debatable that the Wallabies have appropriate players to run it at test level. It is likely that some compromises will need to be made.
One such compromise might be that the backline simply cannot play flat at all times. If poor forward momentum is being provided by the forwards, then the backs might have to sit a bit deeper to have space in which to work, or alternatively adopt a more kicking game plan.
I would rather see the game plan as you describe, but for the life of me I cannot see we have the forward power atm to implement it. We don't appear to have the backup props required, our locks don't play with the required aggression and if Will Skelton is the only option then we will continue to have very poor ball, or none at all, from set piece, and our back row also depends on who comes back from injury. Fardy is our best No 6 but doesn't play a similar game to Potgeiter, Higgers plays similarly with ball in hand but not with the same number of involvements and McMahon and Jones are works in progress. Hooper is almost perpetual motion but I would think Pocock would suit the Cheika game plan better if he returns to top form. Questionable. No 8? Palu, but will he stay injury free? McCalman has surprised almost everybody this tour but he is not really the line bending or breaking hard as nails No 8 that I think is required for this game plan.
I think Cheika has some very big challenges ahead of him and I won't be surprised if he has to modify his approach a bit before the RWC.
