ISU had more yards, I'll give you that. However, Iowa's offense was more effective.
YPA - Iowa 6.07,
ISU 5.77
TD/INT - Iowa 17/7,
ISU 9/14
YPC - Iowa 3.5,
ISU 3.1
YPR - Iowa 11.5,
ISU 9.6
Iowa averaged 18.5 PPG,
ISU averaged 18.1 PPG
Iowa also had far fewer turnovers than
ISU.
You can try to make the argument that
ISU played against great defensive opponents, but being stagnant against UNI, Kent State, Texas Tech, Missouri, and Iowa. But really, again, that's an idiotic argument. If your only argument is "yeah, well, it's easy, because
ISU plays in the much harder Big 12, therefor their stats are more impressive" your only argument, then I don't know what to tell you. You obviously aren't a very knowledgable sports fan if that's your only argument. Because, basically, no matter what the statistics, no matter what the conference does, they'll always be poor in your opinion, and that will forever be your invalid argument.
So really, an argument can be made either way for the worst offensive team, but given the fact that Iowa turned the ball over less than
ISU and scored more points per game than
ISU, I think it's a valid argument that
ISU's offense was no better than Iowa's.
