Week 15 Cumulative Results



The reason why cumulative results are not to be viewed as a Power Rankings is evident as the 2008 seasons heads well into December on the final stretch run to the Playoffs. Teams like Carolina, Philadelphia, and Dallas are playing well and developing towards the end of the season. Their cumulative scores are rising, and they are the ones emerging from the pack in December. I run several spreadsheets looking for changes in how teams are rising and falling in the cumulative standings. First Derivative change is how we can distinguish emerging teams from those that are falling off at the end of the season. As teams that have developed their rushing attack over the course of the season emerge, we can see them rise in the rankings eventhough their cumulative score may be towards the bottom of the rankings. Changes in the rankings are significant and reveal why these rankings are NOT a Power Rankings.
