Defensive Hog Index

Through Week 1 of the 2011 Regular Season

ABOUT THE DEFENSIVE HOG INDEX: The Defensive Hog Index is our effort to quantify which team has the best defensive front in football. It's proven a huge indicator of success since we introduced it during the 2007 season: teams that are better in the DHI are 25-8 in the playoffs over that time, and the No. 1 team in DHI has won the Super Bowl twice (2007 Giants and 2008 Steelers).   
This isn't rocket science, folks. The Defensive Hog Index simply looks at at each team in three major, easy-to-understand categories and ranks them by average in these categories.
The top defensive front is that which posts the highest average rating across the board. The Defensive Hog Index is based upon these criteria:
YPA – Yards Per Attempt. So simple, even you can understand it. This rates a defense's ability to stuff an opposing ground game; NPP% Negative Pass Plays, expressed as a percentage. This is how often an opponent's pass plays end in either a sack or interception. Defenses that get after the quarterback and overwhelm the opposing offensive line naturally force sacks and INTs. These negative pass plays are calculated as a percentage of attempts. So if a team foces two sacks and two INTs in 40 pass plays, their NPP% will be 10 percent (4/40); 3down% - Opposition success rate on third down. The lower the percentage, the higher the defensive success.
Week 1 Defensive Hog Index overview
Big Rex Ryan and the New York Jets enjoy dreams of defensive dominance in 2011 and, if the Week 1 performance of their Defensive Hogs is any indication, those dreams are within reach.

The Jets bottled up the Dallas ground game in their 27-24 victory, allowing just 2.46 YPA, the stingiest mark of Week 1. New York also forced Tony Romo into a Negative Pass Play (sack or INT) on 12.5 percent of dropbacks.

The Chargers, meanwhile, tied Pittsburgh atop the Defensive Hog Index in 2010. They're only No. 16 on the DHI after Week 1, but still keep your eye on them. San Diego forced a league-best Negative Pass Plays on 17.65 percent of dropbacks against Minnesota in Week 1. Super Bowl champion Green Bay topped that indicator in 2010, even as they finished a mere No. 10 overall on the DHI.
