There wasn't much change after Week 9, either. The only difference is that Oklahoma is on the upswing after upending Texas Tech at home, and the Red Raiders have fallen out of the Top 10. That will change in due time as the upper-tier Big 12 teams continue facing off against each other.
So how did the four Big 12 teams in Bleacher Report Top 25 fare in the national polls this week?
Ben Kercheval's B/R rank for each team is listed in italics.
Baylor (7-0): No. 6 (BCS); No. 5 (AP, USA Today)
The Bears' national title hopes are clear: keep winning and hope undefeated teams ranked ahead of them start falling as the season goes along. Baylor's next game against Oklahoma (Nov. 7) will be its first major test and the Sooners are coming off a nice win at home against Texas Tech.
Baylor has been more dominant than any other Big 12 team and it's not close. Despite the soft schedule, that can't be ignored. We'll find out soon enough if the Bears can stay that way—and whether they really belong in the national title conversation.
B/R rank: No. 5
Oklahoma (7-1): No. 10 (BCS); No. 13 (AP); No. 9 (USA Today)
The Sooners deserve to move up after their victory over the Red Raiders. Week 9 was also the best Oklahoma has looked all season, especially on offense.
If Oklahoma can beat Baylor in a couple of weeks, the Sooners become an intriguing outsider in the BCS title conversation since they have the best non-conference win of any Big 12 team, against Notre Dame.
B/R rank: No. 8
Texas Tech (7-1): No. 15 (BCS, AP, USA Today)
It's hard to drop Texas Tech too far for losing a one-possession game on the road against an opponent like Oklahoma. Are the Red Raiders a Top-10 team? It doesn't look like it. But are they somewhere in the Top 15? Sure.
Tech's remaining schedule doesn't get easier with games against Oklahoma State, Baylor and Texas. No one should be counting Kliff Kingsbury's team out of anything yet, but they have to play smarter and more disciplined than they have over the past few weeks.
B/R rank: No. 13
Oklahoma State (6-1): No. 18 (BCS, AP); No. 12 (USA Today)
The Pokes found a running game with Desmond Roland in a 58-27 win over Iowa State. That could finally make Oklahoma State's offense more potent. The question is whether the Cowboys will be able to run on teams like Texas, which has shored up its run defense significantly since Greg Robinson took over.
Oklahoma State hasn't played like a Top-15 team in conference play yet—at least not against teams not named Iowa State. OSU can change that perception by beating Texas Tech in Week 10.
B/R rank: No. 17
