Ratings Trends and Charts

Computer ratings are great in that they process a bunch of data and spew out a rating, but a simple number or ranking oftentimes doesn't tell the whole story.  Some teams are very consistent and others are all over the place and there may be trends in teams steadily improving or not.  One can look at standard deviations and raw numbers over time, but there is nothing like visualizing it.

To that end, I've created charts for all NFL and FBS teams that show the current rating for reference, each weeks rating for the year, and then dots representing how each game contributes to the overall rating.  The dots are interesting as the size represents the weight of the game and green represents games won and red games lost.

Below is the chart for New England.  You can see that after a slow start and some up and down games, they've been pretty consistent even with the loss to Indy.

If you are interested in seeing all the charts for all NFL and FBS teams, sign up for the weekly newsletter which includes the charts along with details on picks against the spread which despite some up and down weeks are still doing pretty well at 357-278-10 for college and 91-65-4 for the NFL.  The price for the newsletter has been cut in half to $10 for the remainder of the season so sign up and take advantage of the offer today.
