I get what you're saying but you're assuming there's a guy out there now that can do it better. I don't think there is. Wrestling seems to be dynasty prone and I think since Iowa had arguably the first ( I guess Oklahoma State sort of had one but I think they had more runs than a dynasty if I'm not wrong) and that has made the fanbase restless when they're not challenging.
Look at when Gable left, Iowa won 3 titles in the next three years then had an 8 year gap until they won three in a row under Brands. Then they were 3,3,4,4,2,5,4,3,4, No final, 1, 3,2, and 5. And that five might be 2 without the unexpected loss of the guys caught up in the gambling issue.
And as MSU said, who does better? So Iowa doesn't lose those people they still are back in the crowd. When these dynasties happen, everyone battles for what's left. It doesn't mean you don't try to get better, but you also don't help yourself by making rash decisions.
