I think a lot depends on Greg Holmes staying fit for the bulk of the season, after some various injuries over the last few years.
Holmes is a great scrummaging prop who is also a great ball runner: he should be the Wallabies choice LHP when fully fit, IMHO. Holmes, Horwill and Houston are all good hard running forwards: perhaps Edwards will improve with a proper professional off season under his belt.
Luafutu is also a good ball carrier I think, assuming he gets a run somewhere. MMM is also good all around the park.
Hardman is not a strong runner per se; his strengths are in the set piece and in tight. Hanson or Fainga'a seem more open players who may come on in the last 20 for fresh legs.
With Lucas and Barnes there is enough tactical kicking to cover any weakness in Cooper's play there, but if he has also played fullback in the past, I'd be surprised if his kicking was not better than he shows, and he just loves to run (or skip) the ball.
Please please please give Turinui lots of one on one with the tackling coach.
Speed to burn out wide with Hynes, Ioane and Davies.
