Those games don't mean anything. You try coming off emotional wins against teams like Iowa then turn around and play some scrub program during finals week.
Plenty of good ISU teams have struggled with teams that bad.
Might have been the Royce or Kane-Ejim team that barley beat Mississippi Valley State then turned around 2 weeks later and ran Kansas out of the building.
In the context of that season ISU had already lost at Drake and to UNI in Hilton.
