You can't eliminate luck of the draw but at least if it is luck it will be fair. IMO that's as much as you can practically ask for.the focus in much of this thread is misplaced.
teams playing each other once at home or away in a 17 round season doesn't improve or even out anything in a given season.
every team playing each other twice over x number of years doesn't improve or even out anything in a given season. as an example, you'd rather get St Kilda twice in 2013-14 rather than 2010-11.
the main issue will still exist. the comparison of teams which play different opponents and/or different home and away conditions, but are still compared to each other in the same ladder.
