Zac D going with the Tigers second ruck, and into the ruck with him, may not be a bad move. Zac using the big fist instead of the nice neat palm may be our wildcard. As has been mentioned before it is not easy for Sandi to go the big fist, as the umps do not allow him to jump at a ruck contest so he doesn't get the momentum needed for an effective 40 mt punch forward.
Ibbo could well handle sooky again, leaving Luke to take the tall for the tigers. Spurr in will be a big inclusion from the last time we played them as well.
