What's up with Washington
The formula for weighting different weeks is also one of the reasons why Washington is still at number nine in our power rankings, even though they didn't play well against Arizona. Washington's biggest win of the season, by far, is that 52-17 rout of San Francisco -- seven weeks ago. In next week's ratings, that game drops in importance, so if Washington doesn't establish itself as a true playoff contender with a convincing win over Dallas, it will drop. As I said, these changes are usually pretty smooth and hard to notice, but this change happens to be one of the exceptions.
There are two other reasons why Washington is higher in our ratings than elsewhere: schedule strength and fumble recovery. You'll notice that when we don't consider these issues, Washington's rating under "unadjusted" is 15, much more in line with public perception.
