Just on the JOR omission, remember the coaches want players to play their role not a position. While he may have accrued some acceptable stats if he didn't perform key parts of his role (that we aren't privy to) then that could be the reason he's been dropped.
Good to see Whitecross named. Don't think he'll make the team this week though.
My guess for tomorrow evening:
IN: Mitchell, Gibson
OUT: O'Rourke, Frawley
And then an hour or two before the game Sunday:
IN: Hartung
OUT: Hill
OHawk is struggling with fitness and being able to run out games. I think this is the first reason he might struggle to keep his spot.
