KK I believe we turn it over because we are so static in our tall forwards. Players have to start in the forward line and lead at the footy, not just stand where they think it will land and wrestle an opponent til it gets there, or be running in just before the flight of the footy clogging up space.
That is also the problem with our kicking from defense, all our forwards are up the ground so no-one has a clear space to lead into. The kicking has to be pinpoint, rather than to grass in front of the teammate, because there is no grass (space) in front of him. Players kicking out under pressure need the margin of error that space provides. Look at Walters when he plays forward of the ball, he forces the rest of his teammates to leave him space, then he uses that space, not many kicks to him are lace out on the tit, but because the teammate only has to put the ball in space in front of him, he has a much greater target area and more margin of error.
