Personally, I think Kill out at Minnesota is an ISU opportunity. There's only so many good players to go around in the midwest. I thought UW and UN changing coaches is an opportunity for Iowa going forward. Heck, Illinois too, though I think Cubit might get that job full time. Bill Snyder ain't getting any younger either.
What I'd like to know is...are there any ISU related guys out there coaching-wise that are replacement opportunities? I honestly don't know. Otherwise, you're probably looking at scooping up an assistant or lower level guy (MAC, FCS) - and knowing how the B12 winds are blowing program-wise, they're going to want a guy who emphasizes something similar to the Baylors of the B12 world stylistically speaking.
Say Briles' kid assistant for example. A Brock Speck type might also make sense.
That's what ISU faces here. Who are you going to convince to come to ISU if you make a change?
The report when Mangino was announced that I heard on radio is Mangino and Rhoads never meshed well but kept it behind the scenes. Maybe a QB squabble involved was the biggest driver in all this.
