Assuming Wing and Champion are unavailable.
1/ Wesser
2/ Merritt
3/ Best
4/ Talanoa (I honestly believe he's a better centre than winger anyway, especially as his hands let him down so often when scoring opportunities present themselves.)
5/ Simpson
6/ Sutton
7/ Sandow
8/ Asotasi
9/ Luke
10/ Crossman
11/ Stuart
12/ Pettybourne
13/ Fa'alogo
14/ Falloon
15/ Kidwell
16/ Greenfield
17/ McPherson
Crossman and Pettybourne have both impressed me recently. McPherson can cover the backs in case of injury. If only Kidwell can cut out the silly penalties, he provides good experience and aggression from the bench (which is needed when Roy comes off especially).
Cleal just doesn't rate for me.
McQueen could potentially come in for Simpson, I guess. I didn't see too much in Corrigan yet ... he's a longer term prospect, I think.
I'd personally like to see a continuation of how JT was using Luke Stuart last year. If he's up for the work and punishment, I loved how he rotated from the second row into the front row when Geddes came off. It's one of the reasons why his stats were so good last year and if he's up to it, I reckon they should keep going with it.
When Wing comes back, that will free up yet another bench spot, as Falloon will not be needed as a back up hooker. That would allow the inclusion of yet another big boppa or maybe someone like Capewell who can play a bit of an impact role (as well as cover from 1-7 plus 9).
I think the team will be especially well balanced when Wing is fit. I think Greenfield would be the first player dropped unless he has been training particularly well ... he needs to show that he can play at his best consistently. Simpson would go out to accommodate Champion when he's fit.
