Personally, I'd go with:-
1. Myler
2. Fussy
3. McDonnell (albeit never seen him play)
4. Handley
5. Olpherts
6. Austin
7. Sezer
8. Holroyd
9. Leeming
10. Tetevano (I'd have Walters ahead of Tetevano but know there is no chance of that)
11. Gannon
12. Martin
13. Smith
14. O'Connor
15. Lisone
16. Walters (prop / 2nd row cover)
17. Sangare
Smith has mentioned Olpherts in the centres a lot and thus, I suspect he will be centre. Likewise, I think Smith likes Martin in the centres so suspect he will be the other centre. Personally, I would prefer Martin at 2nd row given Bentley is already missing. Likewise, I understand McDonnell is a 2nd row / centre in any event (I get the impression he might be an Ablett type centre).
Is Lisone not more of an impact prop rather than starting prop?
I doubt Walters will be included given there are already four other props (unless Tetevano is 2nd row), however, even then Donaldson may get the nod ahead of him.
Always hard to predict when it is the first game of the season. Fussy and Olpherts might not even be fit. There would be no surprise if any of Roberts, Tindall or Ruan were named in the 17.
