Honestly, it's not that hard. As soon as a behind is kicked, the nearest player runs his arse off to get the ball, promptly turns around and kicks it to one of the seven Melbourne jumpers leading as fast as they can. Speed of ball movement is a defender's worst nightmare, and the longer the kicker-in spends with the ball in his hands, the more time the opposition has to set up its' structures. If I was coach, that's how I'd run it.
