|* Each week EDSFootball.com will rank all 32 NFL teams based on 8 separate statistical categories. Unlike most "Power
Rankings", our index is based on statistical performance only in an attempt to remove any biases that enter into other
sources' Power Rankings.
The statistical categories include won-loss record, scoring margin, offensive yards per game (ypg) - defensive ypg,
offensive rushing ypg - defensive rushing ypg, offensive passing ypg - defensive passing ypg, turnover differential, total
scoring margins in losses and strength of schedule.
** Scoring range is 256 (best) to 8 (worst) except in week 1 when strength of schedule is not included. In week 1, the
best score possible is 224 and the worst score possible is 7.
Note: scoring in 2007 was reversed; the lower the score, the more dominant the team.
