Here is my hacky visual attempt of where I think we struggle when we move the ball out of defence and when the oppositon move out of defence. First image is when the opposition bring it out of defence, second is when we bring it out of defence.


When the opposition have the ball in their defensive 50 IMO we flood too early...look at the amount of space that is available from half back up until the wing. This allows the opposition to bring the ball up the ground under no pressure. Once they have the ball at half forward, they still find space to kick short to someone inside 50. This indicates to me that even though we are flooding, we aren't concentrating when it comes to the opposition's final kick inside 50. Look at the amount of times Sydney had it about 65m out but were still able to find someone inside 50 even though we had heavily flooded.
This gets back to the initial setup and what is shown in the second image. We should be pushing more numbers up the ground so that there isn't the space for the opposition to bring the ball up to the half forward line. It's as though we are conceeding the ball until 60m out from our defensive 50.
When we have the ball the opposition push numbers up to the wing AND push numbers into the middle or across to the other wing...I can't do stuff in paint very well but basically they flood the wing and the middle of the ground. If we switch the ball they then move players to the other wing.
Yet all we do in this situation is bomb the ball down the line and hope to win the ball when it hits the ground. Against a team with bigger bodies like Sydney we struggle.
What other options does Ratten have to bring the ball out of defence? It's very stop start...take a mark, look up and see nothing there and then chip it sideways to Waite or Thornton. You see some teams create space by having players lead into the centre of the ground, and then one or two players leading back out to the wing where space has been created. To me there doesn't appear to be much strategy to moving the ball.
