For the sake of throwing something up here I'd go:
Hookers - Folau Fainga'a, Brandon Paenga-Amosa, Tolu Latu
Props - Taniela Tupou, JP Smith, Scott Sio, Alla Ala'alatoa, James Slipper
Locks - Matt Philip, Izack Rodda, Adam Coleman, Lukhan Salakai-Loto, Luke Jones
Backrow - Isi Naisirani, David Pocock, Michael Hooper, Jack Dempsey
Scrumhalf - Will Genia, Jake Gordon, Nick Phipps
Flyhalf - Matt To'omua, Quade Cooper
Centres - Tevita, Kuridrani, Samu Kerevi, Reece Hodge, Kurtley Beale, Jordan Petaia
Back 3 - Dane Haylett-Petty, Israle Folau, Marika Koroibete, Jack Maddocks
That's 31. I recognise there will be perceived bias here and it may be actual bias, if it is it was unintended.
Players who played this year but are dumped are: AAC (Adam Ashley-Cooper), Foley, Timu, Ainsley, Powell, Hanigan, Samu, Simmons, Naivalu, Kepu, Banks, Robertson.
Players who feature who did not play this year are: Naisirani, Smith, Slipper, Petaia, Jones, Philip, Cooper.
Obviously it is all form dependent and that is nowhere more relevant than Cooper over Foley. Basically that spot should go to whomever has the better Super Rugby season.
