There's a bit of second year syndrome about Wilson I think, but I'm not too worried. I still think he gets the Wallaby 8 jersey against France.
The McReight vs Hooper looms as a fascinating battle. It wouldn't shock me to see them both starting at some point, though given Wilson's lineout involvement I'd suggest they'd have to have a different third wheel, like Samu or Hanigan.
McReight offers plenty of things we like in a 6, bar the lineout. He's physical, aggressive, works hard, runs and tackles well. His ball-running and support play separate him from Pocock in the 'Pooper' system, which was never quite what we needed from a 6/8. Fraser could be a bit more suited to that role.
Clearly they are both very talented, and if we don't have a standout option at 6/8 then I'd give it a crack to see how it goes.
