Saban has a lot more advantages over Chryst than Wisconsin has over Iowa. Like others have said, look at Wiconsin pre Barry
Look at Iowa pre-Fry. They won a national championship and Rose Bowl in 1958 and another Rose Bowl in 1960. Then went 20 years without ever having a winning record. Iowa has had a damn good run for 39 years now, one that a lot of schools wish they could have.
