You can't prosper with just Iowa recruits but if you are able to get Iowa Mr. Basketball and the runner up every year you are going to have some talented players. Would have been interesting to have Harrison Barnes and Doug McDermot the year they graduated stay in Iowa.
If Iowa got all the best Iowa kids every year, they'd contend for the Big Ten title every year. Just because you're from Iowa doesn't mean you can't play anymore than just because you're from Michigan or NY or California or Ohio means you can. The talking heads don't get that, but I'd think most Iowans would. The evidence is pretty clear, but I know facts are not cool.
The span from Barnes/McDermott to Jok has to be the best collective 4 year run for Iowa talent ever.
In between those years you had Uthoff, Washpun, Woody, Gessel, Paige, Lohause, Morgan and Dondre Alexander.
And not a single one went to ISU.
If you could have got them all on one team you'd probably have a couple final 4s.
