Hawk Blogger 2011 Power Rankings – Week 3

PRIMER
Power rankings are always debatable. I don’t buy into the gut feel methods most places use to determine their rankings, so I developed a formula a few years back that attempts to take at least some of the subjectivity out of the discussion. My approach is simple, I measure offensive and defensive efficiency based on the Yards Per Carry (YPC) and Yards Per Attempt (YPA), as well as points scored and points allowed. The formula to calculate “Team Strength” is as follows:

(YPC (offense) + YPA (offense) + Avg Pts/Game Scored) – (YPC (defense) + YPA (defense)+ Avg Pts/Game Allowed)

The formula has proven to be a pretty accurate predictor of success. Even in the first week of the 2008 season, 5 of the top 10 ranked teams were playoff bound. As with any statistic, it becomes more meaningful as the sample size grows. Only 3 of the top 10 teams from week one of 2010 made the playoffs, and a team as low as #27 (Atlanta) was a league power. Usually, these become most meaningful after week 3. In 2007, 9 of the top 10 ranked teams were playoff teams, with the lowest ranked playoff team coming in at #15. In 2008, 8 the top 10 were playoff teams, with Arizona being the lowest ranked playoff team at #19. In 2010 8 of top 10 teams from week 3 made the playoffs.

THIS WEEK
These rankings start to mean something this week. By this time last season, 8 of the top 10 teams ended up making the playoffs. That has been relatively consistent for the past three years of doing these rankings. That’s great news for Detroit, Buffalo, Houston, Tennessee and San Francisco. Odds are that three of those five teams make a surprising playoff run. On the flip side, no team below #18 (New Orleans) at week three turned their season around and made the playoffs. Atlanta, Chicago, Tampa Bay and The Dream Team should be feeling the heat.
