Iowa has a system to develop these kids. They will win more games than they lose if they pull a sufficient number of the low and mid 3*s up to being able to compete at the Power 5 level, which they have done over the years. We will see in the next couple of years whether NU's plan of developing even better recruits to compete for conference titles and playoff spots works out.
Pelini was 3-1 against Iowa when they went 26-25. Riley/Frost are 0-4 against Iowa when they went 35-16. The bottom line is that NU has recruited at a significantly better clip than Iowa since before NU's move to the B1G, but Iowa has gotten a much bigger bang for their recruiting buck than NU over the past few years.
We will know NU has a arrived back as a legit program when the Iowa game in no longer a yearly nail biter, but a game NU fully expects to win.
