Here's the rest of their schedule:
@Rutgers
Maryland
Indiana
@Ohio State
Rutgers
@Wisconsin
@Nebraska
At 19-5 the possible end records are 26-5, 25-6, 24-7, 23-8, 22-9, 21-10, 20-11, and 19-12. Obviously nobody knows how everything will turn out but Maryland and Wisconsin are the two ranked teams on that schedule. It is plausible Iowa could lose both those games. Rutgers has turned the RAC into a house of horrors for a couple of teams this season, Nebraska has the kind of guards who can make life miserable for Iowa, and Ohio State always plays well in Columbus. If you were to corner me I'd say 23-8 or 24-7 are the most likely outcomes. Iowa I think has done too much to finish with any of the last four records. They would need alot to go their way for 26-5 or 25-6 to happen.
