Iowa is benefitting in the NET from their predictive metrics. The predictive metrics are inflated by their overall efficiencies being really good due to them beating the eight sub 300 teams by an average winning margin of 30.25 points. The NET does not cap efficiencies which are intrinsically impacted by margin of victory. They are perhaps the most extreme outlier of any team in the country right now. It is what it is, the committee will weigh both their metrics and actual resume. If they sweep the Minnesotas, Nebraskas, and Penn States they'll be fine and work their way to a .500 or better B1G record. That gets them in the dance just probably not a very good seed because they literally don't have a single good win.
