NFL Week 16 Stop Factor rankings: Bears extend lead over Seahawks

Sports Stats ‘on Tapp’ is a sports statistics blog published with a focus on stats that go beyond the numbers.

Barring a total collapse against the Detroit Lions, it looks like the Chicago Bears defense will end the season as the NFL’s number one Stop Factor defense. The Bears hold na almost two point lead over the Seattle defense going into this final week.

(The Stop Factor is based on the premise that it is the defense’s job to stop their opponents from scoring on each possession. To get a team’s STOP Factor, you divide the number of times a defense stops the offense from scoring – offensive unit TD or field goal – by the number of total possessions by the opposition.)

Following is each NFL teams’ Stop Factor. Listed is how many times each team stopped the opponents from scoring, the number of possessions their opponents had, and the percentage of possessions that each team prevented the other team from scoring (stats are through Week 16 games).
