Perfect gig for Matt Campbell. He'd go 10-2 every year, with one loss to Notre Dame, and one loss that costs him a conference title.
Even though he can't beat his rival, it doesn't matter as much at places where the biggest rivalry game is OOC; as is the case at both Iowa St and USC. His inability to win a conference title is not as big of a deal in the CFP era either, particularly at a place like USC where you can rack up style points pretty easily.
