We have another college football preseason top 25 poll. This one comes via Bill Connelly of SB Nation, which publishes the S&P ratings.

Connelly uses three things to make up his ratings:

Recruiting rankings

Returning production

Recent history

You can view the full explanation for the model here.

Here’s the top 25:

Alabama Georgia Clemson LSU Oklahoma Florida Ohio State Auburn Michigan Mississippi State Wisconsin Notre Dame Texas A&M Penn State Washington Missouri Utah South Carolina Miami Oregon Tennessee Oklahoma State Michigan State Boise State Iowa

The most-notable aspect of this list, arguably, is that Clemson is not No. 1 or No. 2. The Tigers are the reigning national champions, coming off a blowout win over Alabama, and will likely be the preseason No. 1 in the official top 25 polls.

Alabama and Georgia are weighed more favorably in this rating system, though, mostly due to the recruiting rankings and the returning production aspect.

Auburn and LSU are two other teams that are ranked higher in this model than they’ll likely be in the official preseason top 25s.
