Rivalry Week caps the 2025 regular season on November 29-30, delivering a slate packed with historic matchups that could shake up College Football Playoff bids, conference titles, and bragging rights for years. With the expanded 12-team CFP format, these games carry extra weight—wins here often mean postseason glory, while losses sting extra deep. Expect chaos: emotions run high, underdogs rise, and "throw out the records" feels real. The action kicks off Friday night with the Lone Star Showdown's return and peaks Saturday with a marathon of classics.
