CHFF analyzes the playoff alignment problem

And comes to an interesting conclusion:

In the expansion and realignment of 2002, the NFL spit up the lessons in moral hazard it should have digested in the late 1960s. So what we have today is postseason chaos on an even larger scale: a system in which 8-8 teams host playoff games against 12-4 teams, 9-7 teams host not one but two playoff games, 11-5 teams sit at home, and a pair of nine-win teams battle for the right to go to the so-called Super Bowl.
