At the risk of putting a few noses out of joint, I think selecting either Tomua or Godwin is a very conservative pick, more like what the Poms or Africans would do rather than the traditionally more ambitious Wallabies.
This state of affairs really only came about through the back door to cover defensive inadequacies on the part of the blokes playing 10, namely Cooper and Beale.
What are the outstanding characteristics of Tomua? A strong defense. An ok runner and kicker, but he's not going to frighten anyone in the top international teams doing either.
I think we need more out of the Wallaby 12, either a bash and barge merchant, or a proper creative player. Someone with genuinely threatening offensive capabilities, like Kuridrani or Lealifano.
