Alabama and Oklahoma State have jumped into the top five in this week's AP Poll, out Sunday.
Week 10 was not a good time to be an undefeated team, as five of them took their first loss of the season. On Saturday, LSU was overwhelmed against Alabama. Michigan State lost in questionable fashion to Nebraska. TCU couldn't hang with Oklahoma State. Memphis saw its undefeated hopes dashed against Navy, and Toledo earlier in the week fell to pesky Northern Illinois. Your remaining unbeaten squads heading into Week 11 are Clemson, Ohio State, Baylor, Iowa, Oklahoma State and Houston.
Elsewhere, Arkansas beat Ole Miss after a thrilling, outrageous, totally legal fourth-down conversion in overtime. Auburn had a nice upset against Texas A&M, leaving Aggies fans displeased with coach Kevin Sumlin.

The College Football Playoff's selection committee will release its second batch of rankings on Tuesday. This week's other polls don't matter as much as the committee's list, but they could hint at what will change in the next version.

The four rankings used here
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 November. Usually comes out on Sundays about 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 this is the other big one. Releases early Sunday afternoons.
The Massey computer composite: A collection of ... every rating out there, which will be included as soon as it is updated. 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.
Bill Connelly's S&P+ ratings: Connelly's efficiency- and explosiveness-based metric parses each team's performance and adjusts it for strength of opposition. These ratings ultimately become part of each FBS team's advanced statistical profile. They're entirely computer-generated and don't signal an agenda against anybody's favorite team.
