There's a slightly new wrinkle this year though. As before, I used my final MDS Model ratings from last season as the base, and then factored in ESPN's Preseason FPI and the S&P+ projections (which are now housed over at ESPN with Bill Connelly leaving SB Nation), but this year I've also included Ed Feng's rating system from The Power Rank. Once the season starts, this "preseason" rating will be faded out as the season progresses, carrying less and less weight with each ensuing week.
As I have in the past, I missed Week 0, but got these ratings out before the first full weekend of games.
In the below list, the "Trend" indicates whether the respective team's new ranking rose or fell relative to last year's preseason ratings. No team movement in or out of FBS this year though!
My goodness are Alabama and Clemson evenly matched, and in a class of their own:
