The question is, with the extra space, will the designated kickers (particularly those with "long" legs) be more likely to kick long? A long kick is going to score more SC and will score points regardless if it results in a mark (as long as it's not picked off by the opposition) but by kicking long, the opportunity for slooty chipping around is reduced. My gut says the defensive mindset of most team rules will see the space used to maintain possession with the long kick still being the last resort.
If only Fletch was still playing......
