17 rounds is fairer. Alternate whose home and whose away each year. Similarly whether getting 8 or 9 home games.So what's the thought that TV deals aside, it's possible a fairer comp now with teams having extended runs at home (other than the ususal suspects at the G), makes you realize how lopsided it is.
So one year 9 homes against 9 sides and eight away games against the other 8. Next year 9 away games against the sides you played at home the previous year and 8 home games against the sides you played away the year before.
Of course it's not perfect as you may end up playing a bunch of good sides away and poor sides at home or vice versa, but it's fairer then the current system. Unless it drops to 16 teams and 30 rounds it's as fair as it'd get. TV rights precludes it, outside of that it'd also help with a later start to the season (so AFLW doesn't run into it), being able to program multiple byes (say after rounds 5, 9, 13 and 17) and still have September finals.
Given all the problems with the existing draw, including the continual s**t games against low drawing sides every year at AO, I'd jump at a 17 round season structured like this. So what at only one Showdown a year and only every second ours? Not getting GWS, Freo, Melbourne, Saints on a Sunday afternoon most years would more than compensate for it.
