Tracking the playoff trends

Over the course of many years, I keep a data-base for various trends in the NFL game. This morning, let's update two of the most interesting, Home Field Advantage and Seeding, and the Turnover Battles:

Home Field Advantage and Seeding:

The table you will see below is a simple tracking of seeding and home field advantage in the NFL playoffs since the field was expanded to 6 teams per conference in the 1990 season.

As you might notice, the 2011 column only represents 8 of the 10 games that are played before the Super Bowl (since the final 2 games have yet to be played). In that 22 seasons, the best year for home teams was 8-2. This season, if New England and San Francisco both win on Sunday, that would put the home teams at an all-time high 9-1, which I suppose would suggest that home field means something again. But, given that in 2010, the home teams were 4-6 in the playoffs, that would likely be a rush to judgement and a knee jerk reaction we should resist.

What makes that 9-1 home record all the more remarkable would be that the lone loss would be 15-1 Green Bay losing at home as the #1 seed in the NFC. A quick scan of the NFC side of the table below will reveal that the #1 seed of the NFC Playoffs played in the NFC Championship Game every year from 1990-2006. But, in 2007, when the Cowboys lost in their 1st playoff game, the #1 seed started trending in the wrong direction. Since then, the 2008 Giants, 2010 Falcons, and 2011 Packers have all gone one-and-done.
