Yes we can, because it was a fluke due to the weakest schedule since they split the Big Ten (or any schedule I can think of before that), coupled with getting lucky breaks numerous times during games. If that season wasn't completely surrounded on both sides by 5, 6, and 8 loss seasons then you might have a point.
I enjoyed 2015 thoroughly and it was super special for my 10 year old and I. Wouldn't trade it for the world. But it was anything but indicative of Iowa football.
"The state of the program in general" is 7-8 win seasons which puts you at 4th in the west and 7th B1G overall. Nobody can argue that it's right there in black and white. If you're happy with that perennially more power to you, but that's not success.
And I don't care to look at how many teams are worse or whatever so you don't have to bring that up...it's the defeatist, roll over and die, way to see things. No one ever made success for themselves by counting the number of people who were shittier at something than they were. The only thing that does is made people who suck at something feel better about themselves. It does nothing of substance. That's like someone who runs a 5K and looks at how many people were slower than them instead of how far down the list they were, so they feel like they were fast. That's a little kid attitude.
Do I want things to change? Sure I do. I'd love to have Wisconsin's program. Are things going to change? Nope. Not as long as Ferentzball is around and there's no good replacement out there (for the record and so I don't get accused of hating Ferentz, I am not advocating getting rid of him). But I refuse to act like we're in some sort of eventual track towards the top of the Big10 West. That's for Nebraskans.
