We are not going to change our ruck/midfield set up, because we are worried about Sam Darcy match up. The game will be won in the middle, not by defending high balls into dogs forward line.
SDK will stay where he is, if we need another tall defender then we have COS to play on Darcy.
I’d be surprised if they brought COS in. To me he seems another pre season away from having the body to compete with the senior key forwards. I think it’s more likely we play a team defence with our existing structure which is easier to achieve at KP than at other grounds.
