I'm with Swingpass, incumbency will mean a lot at least for the first test. Nick Frost will be the sole uncapped player imo but he is the future right here and now at lock (is Lonergan capped? FIIK). Extremely skillful and most like Rory Arnold for height at lineout time a nd disruptive influence in mauls along with Darcy Swain.
I expect something like :
Slipper, Fainga'a, Tupou, Swain, Philip, Leota, Hooper, Valetini, White, Cooper, Koreobete, Kerevi, Ikitau, Wright, Banks. Reserves - Lonergan, Bell, Ala'alatoa, Frost, Samu, McDermott, O'Connor, Kellaway.
Lose the first test and I think Scott Sio could replace Slipper in the 23, Porecki could come in for either Fainga'a or Lonergan, Holloway at 6 if either Leota or Valetini bottle it or are injured (what's with Rob V's hammy?), and Petaia could be introduced to the bench for Kellaway or Wright.
But optimistically, test 1 is a win leading to three on the trot.
