Yeah it has surprised me for the past few weeks. In fact, here is the top 5 according to that rating system now:
Seattle
Denver
SF
SD
NE
(The Bills are currently 20th)
That system has had NE consistently fairly high all season so far. They were in 7th prior to blowing out Cinci.
"The New England Patriots’ 43-17 win over the Cincinnati Bengals was the most impressive performance of the week, according to Elo, and earned the Patriots a gain of 29 Elo points."
