12	Anthony Fainga'a
11	Pat McCabe

A few notes:
- still don't think Hynes should/will be our World Cup fullback, but probably still need another year for JOC (James O'Connor). Or perhaps he'll be there year end.
- prefer Diggers used as a roamer on the wing, rather than tied up at 13.
- 3 debutants on the bench in Weeks, Douglas and Hodgson. Douglas the biggest question mark, but one of these 2m youngsters (Kane, Simmons or Hockings) needs to step up for next year, so let's see KD.
- Simmons and Hockings in Oz A, which will be a tough forward encounter v the Poms.
- Lealiifano would've been in As at least, if not for injury. Likely starting at 10.
- Thought about blooding a young openside in Hooper or Fainga'a, but probably not needed just yet. Brown can do the job v the Poms. 
- Higgers had to be in Aust A, but not convinced 8 is his best spot. Leroy was considered, but probably not for long as Dennis also must be in the team, IMHO.
- Henderson, at prop, came close to consideration too. Likewise Fairbrother could've pushed for a starting spot.
- Josh Holmes is probably a bit of a surprise to start, but I think he's the man next most likely to snag a wallaby spot.
- No oldies here. No Waugh, Baxter or Humphries. The latter two could've pushed for a spot, and Waugh due to lack of depth, but no need in this game.
