BYU (6-2) and TCU (5-2), two former Mountain West Conference rivals, will meet tonight at Cowboy’s Stadium in Arlington, Texas (ESPN, 8 p.m. ET). TCU has won the last three games in the series by an average score of 33.67 to 5.67 and have allowed the Cougars to score only two touchdowns in their last three meetings.

TCU enters the game with the eighth-best scoring offense in the nation (43.57 ppg) after beating New Mexico 69-0 in its last outing. The 69 points is a school-record.

The top four teams continue to hold their ground in the weekly rankings. Boise State and Houston remain the top two teams, respectively, as both sport 7-0 records. BYU and Southern Mississippi maintain the third and fourth spots, respectively.

The biggest mover of the week is Toledo, who went from 10^th to sixth after a win over Miami (Ohio). The newest addition to the rankings is Arkansas State, who remains undefeated in the Sun Belt Conference.

Temple dropped out of the rankings after a loss to Bowling Green.

This week there is plenty to watch for among the non-AQ games. Houston’s Case Keenum and Boise State’s Kellen Moore are on the brink of breaking records. Upstarts such as Eastern Michigan and Western Kentucky try to entrench themselves in conferences title chases. Fresno State and Nevada meet for the final time as members of the Western Athletic Conference before becoming Mountain West members in 2012. The night game features possibly the game of the day with Conference USA powers Southern Mississippi and Southern Methodist meeting.

This week the power rankings remain fairly static as the top seven teams remain unchanged. Temple moves up from ninth to eighth while San Diego State (ninth) and Toledo (10^th) move into the rankings.

Central Florida and Western Michigan drop out of the rankings.

With the Big East reeling from the recent defections of Pittsburgh and Syracuse to the ACC and TCU for the Big 12, the conference’s remaining six members announced it will add six teams. Among the schools being mentioned as possible invitees are Air Force, Army, Boise State, Central Florida, East Carolina, Houston, Navy, SMU and Temple.

In the BCS era, only Utah, who joined the Pac-12 this year, and TCU, who will join the Big 12 next season, have been invited to join an automatic-qualifying (AQ) conference while a member of a non-AQ conference.  Each school had played in two BCS bowls as non-AQ schools. So how do the schools being considered by the Big East stack up against Utah and TCU?
