The Big 12 Conference faced significant setbacks during Week 8 of the college football season, underscoring the unpredictable nature of this year’s landscape. Just one week after featuring three undefeated teams within the top nine of the US LBM Coaches Poll, the league saw its leading contenders falter in crucial matchups.

Brigham Young University (BYU), which earned a signature victory over No. 8 Notre Dame earlier this month, suffered a 39-31 double-overtime loss at Central Florida. BYU managed a goal-line stand and blocked a field goal at the end of regulation to extend the game, but ultimately was outperformed by an opponent with a modest 1-3 record against Power Five competition. BYU’s next two games, against Arizona State and No. 9 Utah, will be decisive in determining whether the Cougars remain a title contender or settle for an at-large bid to the College Football Playoff.

Texas Tech, ranked No. 5 earlier in the season, also struggled, dropping a 37-24 contest to Cincinnati after benefitting from a relatively easy early schedule. Despite scoring on a defensive pick-six and adding a late touchdown, the Red Raiders failed to regain momentum after surrendering 21 points in the second quarter.

The performance of Utah, which defeated No. 16 Houston 21-13 behind quarterback Devon Dampier’s 350-plus yards of total offense, provides some hope for the Big 12. However, the league’s chances of placing two teams in the playoff field remain uncertain, especially if Utah does not maintain an undefeated record through the remainder of the season and falls in the conference championship game. Meanwhile, the Southeastern Conference (SEC) is positioned to capitalize with a greater depth of playoff-caliber teams, increasing the likelihood of a three-loss SEC team receiving an at-large bid.

Elsewhere, several teams outside the Big 12 posted notable results. Texas, ranked No. 18, avoided a damaging home loss to No. 7 Ole Miss by holding onto a 34-27 victory. The Longhorns overcame turnovers by quarterback Arch Manning and struggled in special teams, but managed to secure the win through a key defensive stand.

Virginia Tech improved to 6-2 with a dramatic 20-16 road win over Clemson, sealed by a bold fourth-and-1 touchdown conversion late in the game. LSU, ranked No. 21, dominated Auburn 38-17 in a strong offensive showing led by quarterback Sam Leavitt’s 387 yards and three touchdowns.

No. 12 Kentucky also extended its winning streak, defeating Vanderbilt 34-17. The Wildcats built their lead with three consecutive long touchdown drives and avoided turnovers.

However, not all top teams fared well. No. 11 Tennessee fell 31-24 at South Carolina after costly late-game errors, including a failed fourth-down attempt and a critical fumble that allowed the Gamecocks to kick a game-winning field goal. Michigan suffered a 13-6 overtime defeat at No. 6 Indiana, struggling offensively under quarterback Tommy Carr despite a strong defensive effort. Southern California (USC), ranked No. 15, lost 24-7 to Wisconsin in a game marked by inefficient offense and missed field goals.

This weekend’s results contributed to considerable movement in the Top 25 rankings, with seven teams in the top 18—BYU, Texas Tech, Ole Miss, Tennessee, No. 14 Iowa, USC, and Houston—recording losses. Miami is expected to assume the No. 1 spot, followed by Ohio State, while the rest of the rankings are likely to reflect a broad mix of unexpected outcomes. Notably, having three or fewer unbeaten teams this late in October is an uncommon occurrence, last seen in 1977.
