And then there were two.
With Kansas State and Oklahoma both losing last weekend, TCU and Baylor remain as the only two playoff possibilities for the Big 12.
In the third edition of the College Football Playoff rankings released Tuesday night, TCU cracked the coveted top four by jumping Alabama. Baylor, meanwhile, jumped five to No. 7 after smashing the Sooners.
Here's a deeper look at what those rankings mean for the Big 12:
Record: 8-1 (5-1 Big 12)
Playoff committee rank: No. 4
Next big obstacle: Nov. 27 at Texas
Reason for optimism: The selection committee likes what it has seen from the Horned Frogs, whom it jumped ahead of Alabama to the fourth spot. TCU has quality wins over Minnesota, Oklahoma, West Virginia and Kansas State, and a quality loss at Baylor. Considering Alabama and Mississippi State play this weekend and No. 2 Oregon and No. 6 Arizona State would potentially meet in a Pac-12 title game, at least two teams ranked around TCU are penciled in for another loss, too.
Cause for concern: The Horned Frogs don't have another ranked team left on the schedule. So will they be able to hang on to a top-four spot? It also remains to be seen how the committee will ultimately input Baylor's head-to-head edge over TCU. Committee chairman Jeff Long said head-to-head would be a tiebreaker, in the event two teams are viewed as equals. That's not the case now. But it could be down the line.
Whom they'll be rooting for this week: Minnesota to knock off Ohio State. At 7-2, the No. 25 Golden Gophers have boosted TCU's nonconference résumé. But that will stay that way only if Minnesota finds a way to keep winning. That won't be easy for the Gophers, either. Minnesota faces No. 8 Ohio State, No. 16 Nebraska and No. 20 Wisconsin to close out the season.
Record: 8-1 (5-1)
Playoff committee rank: No. 7
Next big obstacle: Dec. 6 vs. Kansas State
Reason for optimism: Even though Ohio State won at Michigan State, Baylor kept its edge over the Buckeyes, and thus the Big Ten, with a resounding victory at Oklahoma. The Bears also should have the opportunity to make another statement in the final week of the regular season when they play host to No. 13 Kansas State.
Cause for concern: The committee has said head-to-head would be one of the factors it would choose in picking playoff teams, but Long clarified Tuesday night that it would be used only as a tiebreaker. At three spots away, the Bears are not close enough to TCU yet for that tiebreaker to come into effect. Even though the Bears have the great win against TCU on the résumé, a soft nonconference schedule keeps bogging them down in the eyes of the committee.
Whom they'll be rooting for this week: Miami to upset Florida State. The Seminoles dropped to No. 3 despite being undefeated, because of how poorly they've looked in many of their wins. The Hurricanes, who have quietly won three in a row, have the talent to knock off Florida State. And a loss by the Seminoles would eliminate the entire ACC from being a factor in the playoff, and move the Bears one step closer to a top-four spot.
