I saw one league that uses weeks 1-3 as playoffs - they set lineups every week, then play regular season from weeks 4-16 to determine playoff seeding. First round in Week 3, Semis in Week 2, Championship in Week 1. Would make the end game very interesting as you would have a real reason to throw Week 16 if you knew that it would get you a team that stunk in Week 3. Would love to try it in a low cost league to see what it was like, but the guy with the worst Week 1 score would have nothing to play for from the jump...
