We’ll add each significant new top 25 here as it shows up.

One week ago in this rankings update, we reminded you CARNAGE WEEK had not yet arrived, but it would soon. Well, here we are: college football’s first CARNAGE WEEK of 2018 just struck. No. 2 Georgia got manhandled by LSU, No. 6 West Virginia caught Ames Madness, No. 7 Washington got knocked out of the Playoff by its suddenly burly archrival, No. 8 Penn State took a Dantonio special, and so on.

In the long term, this weekend will really matter. In the short term, much of the top-25 rankings will look brand new.

Below, we’re collecting updated college football rankings heading into Week 8.

The usual disclaimers apply. The only college football ranking that matters in the end is the Playoff selection committee’s ranking on Selection Sunday, and the committee can change its mind suddenly. It doesn’t even start to release weekly Playoff rankings until around Halloween.

We’ll update each of the following top-25 rankings as they release, and explanations for each of these top 25s is below the table.

Only one of these rankings is made by anyone at SB Nation, so please don’t yell at me personally about any of them, unless that would make you very happy. Only top-25 rankings are listed, though most of these go beyond 25 teams. See below for links.

The Associated Press Top 25

The historical gold standard of human polls. Releases Sundays at 2 p.m. ET.

Bill Connelly’s S&P+ ratings

SB Nation’s favored college football advanced stat, which tends to perform well against the Vegas spread, along with offering much deeper evaluations of teams. Usually releases Sunday afternoon.

The Massey composite

Every poll and rating smashed into one continually updating ranking, more or less. Yep, there are dozens and dozens of weekly CFB rankings! We’ll update it a couple times throughout Sunday.

The Sagarin ratings

A long-running computer ranking that also includes FCS teams. Usually releases early Sunday.

The USA Today Coaches Poll

Doesn’t matter much, and often is more a poll of PR directors than actual coaches.
