Re-ranking 138 college football teams after Week 2: Texas vaults to No. 1, then it gets weird

Key Points:

• Texas is ranked No. 1 after a narrow but significant win over Ohio State, boosting their College Football Playoff prospects and highlighting the value of challenging nonconference games.
• The rankings remain volatile early in the season, with teams like Oklahoma State, Mississippi State, and North Texas making notable jumps due to strong performances and head-to-head results.
• Oklahoma State and Tulsa have risen in the rankings despite earlier losses, based on recent head-to-head wins and quality victories, illustrating the fluidity and complexity of early-season evaluations.
• Michigan re-enters the top 25 after defeating Oklahoma, while Western Michigan also ranks ahead of Oklahoma due to their competitive game against the Sooners, showing the emphasis on actual game outcomes over preseason expectations.
• Several teams, including Iowa, Duke, Wake Forest, and Appalachian State, moved up or down based on recent close games, comebacks, and victories, reflecting the dynamic and unpredictable nature of college football rankings at this stage.
