I see Iowa moving up to #2 after next week. Heck, could even be #1, especially if Clemson falls to NC.
Iowa will have beaten 3 currently ranked teams, including a top ten MSU as well as the only team that beat them. MSU will remain in the top 10 after having beaten a top 10 team in OSU (for their only loss), who is currently beating a top 10 Michigan.
If Alabama beats Auburn, and Miss St loses to Ole Miss today, Alabama will have a win only over Wisconsin at a neutral site as the only top 25, while Iowa beat them in Madison.
Maybe the eye-test continues to win the day, but not if they also struggle against Auburn or worse against Florida.
