Since I see you guys were discussing it, this is how the playoffs work in my money league.
The twelve teams are randomly drawn into four divisions of three at the beginning of the season. There are thirteen weeks of regular season, so you get to play every team in the league once, and the two teams in your division a second time. At the end all the division winners get in the playoffs (determined by overall record, with head-to-head victories followed by overall points being the tiebreakers). The two highest-scoring division winners get byes the first week of the playoffs. The two extra wildcard teams are selected from the non-division winners based solely on total points, without regard to record. 3-10? It doesn't matter.
There are several advantages to doing it this way. First and foremost, you have a 50% chance of making the playoffs. More importantly, there are always teams that score lots of points but end up with a poor record. Under this system those teams (and there's always at least one every year) still get in the playoffs, which is nice since you can't control the scoring other teams do against you. It also evens out any disparity in strength of schedule, at least to a degree. Finally, it takes a long time for even lesser teams to be completely eliminated from the playoffs. At least, that's the way it has worked in our league. The first year we did it this way, every single team in the league was still alive for the playoffs until the last week. There are always two or three "big" matchups with heavy playoff implications at the end of the season.
It's a system we've worked out over the course of several seasons, and everyone's been very happy with it the last three years.
Just FYI.
