Iowa: The Hawkeyes simply don’t have enough firepower on offense to survive the mistakes they made in the second quarter. Iowa would have lost by an even greater margin if the Hawkeyes hadn’t played such strong red-zone defense.
Wisconsin: A defense that has been exceptional all year is better than ever now that the Badgers are forcing turnovers. After getting just four takeaways in their first six games, the Badgers have eight in their last two games. … The Badgers were missing usual starting left guard Josh Seltzner. Michael Furtney started in his place.
Iowa obviously will fall out of the top 10 and could plunge all the way into the 20s after a second straight loss.
Iowa: At Northwestern on Saturday.
Wisconsin: At Rutgers on Saturday.
