I think the best 22 structurally based on 7 Defenders, 6 Midfielders, 2 Rucks and 7 Forwards is pretty settled, other than the final defender position (Jetta, Nelson) and final midfield position (Hutchings, Sheed).
DEF: McGovern, Barass, Hurn, Sheppard, Duggan, Cole, Jetta/Nelson
MID: Shuey, Gaff, Yeo, Redden, Masten, Sheed/Hutchings
RUCK: Naitanui, Lycett
FWD: Kennedy, Darling, Waterman, Rioli, LeCras, Cripps, Ryan
Dunno Bluey, the club has shown a very high regard for Venables subject to fitness and i think Petrol will be on the very near fringes with his blitzkrieg pace.
