I don’t think anyone thought Chizik was going to stick around for long. He was a huge splash of a hire, and an impressive get. I think the thought/hope was that he’d have success and move up, proving it was possible to win in Ames.
Exactly this.
The chizik hire was a statement of "Iowa State intends to compete nationally" and was also designed to juice fan financial support. There was a huge push for increased season ticket sales back then, and it worked. (Anyone else remember the ticket thermometer?)
