You could use the 2007-2011 Gary Ablett strategy, which is handball to someone who's facing away from goal meaning he has to immediately handball back to you, thus earning 2 disposals every time he's on the ball. In all seriousness, develop a great level of endurance, as it will allow you to more easily find space around the ground for picking up easy possessions. Learning some of the tendencies of your teammates as well as just growing in your understanding of how the ball is likely to spill out of a pack or how to read the ball of the ruckman's hand. A good way of getting more of the ball is to have good communication with your ruckman so that you're on the same page as to where the hit out should go for you to anticipate it. If you're a good disposal of the ball as well then teammates will often seek you out given your propensity to use the ball well
Play in the backline for Melbourne-you will see plenty of the ball.
