Amid the excitement of two conferences returning to play, Week 8 brought a critical result in the Big 12 and a massive upset to begin the Big Ten season.
Oklahoma State knocked off Iowa State and trimmed the group of Big 12 unbeatens to two. Later in the afternoon, Indiana celebrated a walk-off two-point conversion to stun Penn State and snap a 42-game losing streak against Top 10 teams.
North Carolina and Michigan also earned victories over ranked teams, but Virginia Tech fell to unranked Wake Forest. Those results headlined the changes in B/R's Top 25.
Our five-man panel of experts—David Kenyon, Adam Kramer, Kerry Miller, Joel Reuter and Brad Shepard—each submitted a Top 25 ballot for Week 7.
