Don't look now, but Iowa is undefeated as it readies for perhaps the most difficult game remaining on its regular-season schedule, Saturday at No. 20 Northwestern (11 a.m. CT, ABC/ESPN2).
Who guessed the Hawkeyes would stand 6-0 overall, ranked No. 17 and 2-0 in the Big Ten? The list is likely short. Before the season, ESPN’s Football Power Index gave Iowa a 2.7 percent chance to win its first six games -- the lowest figure of 12 remaining Power-5 unbeatens.
Iowa survived September unscathed with help from a 57-yard, game-winning field goal by Marshall Koehn as time expired against Pitt.
