Colorado State has quarterback issues. The Rams rank 107th in scoring at 22 points a game. They are not going to dent Iowa's elite defense, which gives up the fourth-fewest points per game in the country. The Hawkeyes have accomplished this against respectable offenses, too, holding Iowa State to 17 points and Kent State to seven points during their last two games.

The Rams also are going to be missing their most dangerous wide receiver, Dante Wright. He isn't expected to play because of a knee injury.

Iowa lacks an explosive offense. The Hawkeyes are conservative and slow-paced. They play a grind-out style that keeps the clock moving.

So it's not a fluke the Under has won 75 percent during the past 21 times Iowa has been a home favorite going 15-5-1.
