Think about this:
Iowa only had 4 wins against teams with an overall .500 record or better; Drake (17-17), UAB(20-13) Grambling(17-14) and Colorado(17-15).
In other words the majority of their wins came against teams with losing records and the majority of those also had losing conference records.
6 of their wins came against teams ranked 249 or worse on Ken Pom.
They had only 2 top 100 ken pom wins; Northwestern #85 and Wisconsin at #70.
Didn't beat any major conference team with a winning conference record.
They had 10 losses by double digits, 9 of them in conference and the other one to Virginia Tech.
