College football strength of schedule: 2025 rankings ahead of CFP release

By Kevin Kelley -

College football strength of schedule continues to be a topic of discussion this season as the second edition of the 12-team College Football Playoff (CFP) approaches. With the first set of CFP rankings releasing Tuesday, let’s take a look at the strength of schedule rankings (SOS) as they stand now.

There are several sources for strength of schedule, including ESPN and the computer components that were formerly part of the Bowl Championship Series (BCS) rankings. Note that these rankings are for strength of schedule to date and will differ from preseason rankings, such as Phil Steele’s.

the SEC was such a “gauntlet” last year too until illinois beat scar, michigan beat bama with nobody playing and bama played everyone and ND beat Kirby Claps and osu beat tennessee and texas #stankey

The SEC still had more players taken in the NFL draft than any other conference.

Better players = better teams.

the B10 is 2 very good teams, 1 maybe very good team, 2 or 3 pretty good teams and about a dozen cupcakes.

Ohio State’s schedule only looks weak because they beat everyone they play making them look weak with Losses…

Jesper the bottom of the list. I mean for team with such tradition and prestige they sure don’t play the schedule they once did and they make the schedule to the point the hard games are early, a bunch of dogs the rest of the way so they have a winning streak going so it looks good at playoff seeding time. If they had balls and joined the big ten or sec they wouldn’t get away with that.
