ESPN's Football Power Index is a measure of team strength that is meant to be the best predictor of a team's performance going forward for the rest of the season. Every week, ESPN will be updating its FPI to compile a ranking based on 10,000 simulations of the rest of the season using FPI, results to date and the remaining schedule.

Oklahoma didn't play this weekend but still climbed into the top four of the FPI rankings this week. The Sooners took over the No. 4 spot that Georgia held last week after the Bulldogs dropped to eighth. The top three ranked ahead of OU -- Alabama, Texas A&M and Auburn -- did not change.

Following their wins in Week 5, TCU and Texas both made noticeable jumps in the national ranks. The Horned Frogs moved ahead of Oklahoma State and up seven spots to No. 22 with their 56-0 win at SMU. Their chances of winning the Big 12 nearly tripled from 3.3 percent to 9.8 percent. The computers have enough respect for TCU's start that the Frogs' wins projection went up nearly one full win to 8.9.

Texas, meanwhile, moved ahead of West Virginia and Kansas State and into the No. 30 spot nationally after its 23-0 shutout of Kansas. The Longhorns are still projected to finish 6-6. Oklahoma State's win over Texas Tech did not result in any movement in the FPI ranks, while the Red Raiders moved up two spots.

Here's how they and the rest of the Big 12 stack up entering Week 6.
