Other than the people inside the Iowa football building and the team's most optimistic fans, few expect the Hawkeyes to pose much of a challenge to Michigan in the Big Ten championship game. Doubts that the No. 18 Hawkeyes (10-2) can upset the second-ranked Wolverines (12-0) are illustrated by the point spread. FanDuel Sportsbook on Sunday listed Iowa as a 22 1/2-point underdog for Saturday night's game in Indianapolis.
