You do not know for a fact that Iowa would NOT sell more tickets if they scheduled better nonconference opponents. But, it sure is worth a try to generate more fan interest AND, more importantly, for NCAA Tournament purposes, it would improve their nonconference schedule strength ranking. Why do you think we are #18 in the NET yet considered an 8 or 9 seed by so many? It's because of our WEAK nonconference schedule.
Your point that Fran & Barta cannot possibly predict the NET rankings of these non conference opponents is flat out wrong. You realize the range for Quad 4 home games is 161-358, right??? Therefore, it does not take a rocket scientist to know that 5 very bad opponents (SE Louisiana , NC Central, Portland State, Alabama State and Western Michigan) were going to be Quad 4 bad. And Iowa scheduled them anyway.
I am not sure how you or anyone can look at the 7 nonconference games that follow and not think we can do better.
And contrary to what you wrote, when you beat 5 of your nonconference opponents by at least 26 points, those 5 teams are most definitely the worst of the worst.
Quad 4:
Home: 161-358
Away: 241-358
