College football winners, losers in Week 8: Big 12 loses momentum, Miami continues dominance

Key Points:

• Week 8 of college football saw major upsets with No. 2 BYU, No. 8 Texas Tech, and No. 15 Iowa all losing, leaving only No. 1 Miami, No. 9 UCLA, and No. 10 Utah undefeated heading into the night games.
• The Big 12 conference suffered significant setbacks as BYU and Texas Tech lost, diminishing the league's chances of securing three College Football Playoff teams and likely leaving only two Big 12 teams in the top 12.
• Miami continued its dominant season, defeating Pittsburgh 52-23 to reach 7-0, with standout performances from quarterback Darian Mensah and wide receiver Malachi Toney, earning Miami its first AP No. 1 ranking since 2002.
• Baylor coach Dave Aranda's tenure appears in jeopardy after a narrow 25-24 loss to Kansas ended a 14-game winning streak against the Jayhawks and highlighted Baylor’s offensive struggles late in games.
• South Carolina gained momentum with a 27-24 upset over No. 11 Tennessee, propelled by quarterback LaNorris Sellers' dual-threat performance, raising hopes for a strong finish despite a challenging schedule.
