Actually, I've given this whole issue a little more thought, and I think Stringer is a chance of being picked as a bench prop for Country as well.
They are weakened in the forwards through injury, and apart from Kite, Bailey and Cusack I don't know of any country props that would be picked ahead of him?
Last years country side for reference:
Luke Patten
Amos Roberts
Matt Cooper
Matt King
Nathan Blacklock - overseas
Scott Hill
Brett Kimmorley - played Anzac test
Peter Cusack
Luke Priddis - played Anzac test
Ryan O'Hara - injured
Andrew Ryan
Willie Mason - injured
Glenn Morrison
Daniel Abraham - injured
Kurt Gidley
Brent Kite
Josh Perry
