They haven’t because Kirk has an inability to recruit or develop top end receivers.
Which wouldn't make the expectation any less unrealistic/uninformed.
For one thing, there are only a handful of those top end receivers (that fans seem to think the game evolves around) in the country. Guess what. Those guys will never end up at Iowa, on a year to year basis.
But for another thing, it's pretty reasonable to assume that there is a 4 year window remaining for Iowa to try to level up, as a program, under KF. There may be a couple add on years. Who knows?
But what Iowa has to do, in the near future, to fight an uphill battle to sustain as a program, let alone level up, comes down to so much more than receivers.
And what Iowa has done, to be the most consistent program in the country over the last 24 seasons, has had almost nothing to do with receivers.
It's just an entirely overplayed narrative by fans. And much of that is to justify, in their minds, what has been completely unjustifyable negativity levied upon the program.
Sure, there's a level of talent just below the handful of top end receivers, that Iowa would love to be able to tap into, at least on a semi-yearly basis. But even those guys, just aren't the difference makers that people believe them to be.
I'm not sure PSU had one explosive pass play in the last few games of their final four run two seasons ago.
National champion Michigan had two long passes of 14 yards, both to RB's, in their '23 big ten title game vs Iowa. I'm not sure they even attempted to throw downfield, IIRC.
The game just isn't what many of you believe it to be. And if it were, there's nothing to show that to be a more sustainable method. Even in the NFL, top end receivers are more like frosting, than an ingredient fundamental to baking the cake. KC was great before and after Tyreek Hill. While the Dolphins, as a program, felt no impact from the presence of Hill.
And fans don't seem to have an answer for how the program is supposed to invest more into receivers without it compromising the program in other areas. Overall, more talent at receiver would amount to more financial investment. Guess what. Funds aren't unlimited. And guess what. I think I'm just fine with how funds are presently being allocated
