The Dockers one wood is their contested footy in the midfield. Dominate that they win; get matched or lose and they lose. So IMO we need to bolster our midfield rotation. They play a taller forward line and will try to stretch us down back so Balta has to play back. For structural reasons, I would also bring back Maurice simply for his forward ground level pressure. As for Sheds, he's been a champion but if he is to get to 300 then it has to be as the sub as he can give us something in short bursts now.
