Iowa doesn't bring in many Jucos and they compete on a Kstate level simply by developing HS 3 star type guys.
They play in a conference that is made to fit for them. A bunch of rust belt schools that have snow on the ground in Jan. Minnesota, NW, Illinois, Purdue etc are pulling mostly upper midwest and great lakes talent.
When it comes to football/recruiting ISU probably has one of the worst conference affiliations in all of college football. You sit in a cold climate and there are teams in conference that may never see a flake of snow, and you have to convince a talented kid from the state of Texas with offers from in state schools, to come north and freeze his butt off. That is a challenge.
The fact of the matter is with departures of CU, Nebraska and Mizzou really hurt ISU. ISU used to pull some decent kids from Omaha from time to time, some of that had to do with snub factor of Nebraska, and kids wanting a chance to play for a team like ISU, so if anything they could show Nebraska what they were missing. It really hurt to lose those teams from the conference.
WV is already starting to see the problems, they too are out of place in the "new" Big 12, more than ISU and it will get harder and harder for them. They will continue to tap Florida for talent, but it may not be as good as it was in the past, given they don't play down there anymore.
ISU survived re-alignment, and that is great. But under the old Big 12 it was hard enough to compete in football, under the "New" Big 12 its worse.
Funny how when it comes to the indoor sports, we seem to be more competitive. Then again a larger portion of the talent for these sports comes from areas, where people are snowed in for several months a year.
