Encourage throwers to identify which side of line is easier to pass to - the one with all their team mates waiting or the side with team mates running in and out?
An additional rule to encourage players to make space for each other.
Mark a pitch as normal with the addition of a line of cones down the centre from one endzone to the other. Each team picks one side of the centre line (left or right) that, when attacking, they are only allowed onto for 5 seconds. There is no requirement for this to be different sides.
As with any game, after a score play stops and teams change ends.
