First of all let's correct your subtle misrepresentation of what I said. You seem like a reasonable guy (and thank you for that, we get plenty of clone, husker and goopher trolls over here) so I'll assume you just missed it.
I wrote that Iowa was: "not a Penn St or Michigan, but it's solidly in that next tier." not... "we're a powerhouse". That clarified, here are a few areas to start your research:
attendance
won/loss record over the last 40 years
annual revenue of the football program
national brand recognition
awards of both players and coaches over the last 40 years
Look around this website and you'll find plenty of links in various threads placing IOWA in the TOP 25 of pretty much every category above (and some I've overlooked). Here are a few starters...you can take it from there.

I got nothin' against the Boilers, I like to see you on the upswing. It's good for the conference and in my experience your fans seem pretty decent. Just sayin' you've got a ways to go until you start showing up on some of those lists.
Good luck! You got us in 2017, we'll be ready this year.
I agree we aren't there yet. But Brohm is quickening this process. I think not this season, but next we will be flirting with the top 25. Maybe that's a bit ambitious. Idk. I think the big ten west as a whole is catching Wisconsin fast. We should have beat them last year... And nebraska...
