Why don't we just make it easy and just play everyone in the league twice (home and away). Then just put the teams with the top 4 records in the playoffs. This would keep it simple and wouldn't take too long (and we can start over with new teams afterwards!).
Also, since we probably all use different sliders/settings, we can make it so that the home team picks all the shared settings. We'll probably need to post all our settings beforehand, as well.
my 2 cents.
