IOWA CITY, Iowa (AP) – Iowa (5-2, 2-1 Big Ten) is still in control of its destiny in the West division.  But a collapse could be imminent if the Hawkeyes don’t make major progress over the next few weeks. Iowa’s rush defense was broken down repeatedly in its last two games. The Hawkeyes are also thinner at linebacker now that Reggie Spearman is suspended for the next two games after he was charged with drunk driving last weekend.

The offense remains among the worst in the Big Ten, and the sudden departure of wide receiver Derrick Willies will further test Iowa’s ability to push defenses. Iowa kicks off a stretch of five games in 28 days on Saturday against Northwestern (3-4, 2-2).
