College football rankings: Composite polls/computers top 25 led by Alabama

We saw relatively little chaos in Week 13, but that was a mostly expected outcome given the lackluster slate (that tends to happen once the November SEC-FCS challenge rolls around). Still, four Top 25 teams lost Saturday (three to other ranked opponents), giving us plenty to talk about.

Florida State put together yet another lackluster performance against an unranked opponent, beating Boston College in the final seconds, 20-17. Ohio State pulled away from Indiana late, but saw their glaring loss get more glaring when Virginia Tech fell to Wake Forest. Ole Miss got blown the heck out by Arkansas, while UCLA, Arizona, and Minnesota each notched important wins over ranked opponents.

We have some answers for you now, as Alabama has overtaken Florida State in the Coaches Poll, while the Seminoles stay on top of the AP Poll. The official Playoff rankings come out Tuesday (here are our predicted Playoff rankings), but we’ll try to hold you over until then with these, which also include two sources of computer ratings.

The Associated Press Top 25: The longest-running and best-respected human poll. Didn’t have any official bearing on the latter years of the BCS, and won’t have any official bearing on the Playoff. Expect it to set the course for the committee, however, as most outlets (including SB Nation) will use the AP’s rankings as the standard until the committee takes over in late October. Usually comes out Sundays around 2 p.m. ET.

The USA Today Coaches Poll: Formerly part of the BCS, and now just a poll. It tends to be more conservative than the AP’s. Though polling athletic departments in order to rank other athletic departments is dubious, we still want multiple human polls in here, and it’s the other big one. Releases early Sunday afternoons.

The Massey computer composite: A collection of ... every rating out there. By including it here, we’re giving extra weight to the two human polls, since they’re already two of the dozens of ratings included in the Massey. It changes over the course of the week as more rankings arrive, so we’ve included the latest version as of publication.

Football Outsiders’ F/+ rating: A synthesis of ratings by smart persons Bill Connelly and Brian Fremeau and our personal go-to overall team stat. It tends to come out later than the others.
