Playoffs

How many teams ought to make the playoffs in a fantasy league?  I tend to think up to 50%, but never more than that.  Some people think that you have to take 4 teams, and play weeks 15 and 16, no matter how many teams your league has.  There are a lot of ways to look at it, but the bottom line is this: make sure your league owners are all on board with whatever changes your league makes!
