I’m thinking much of the delay might be attributable to policies not allowing coaches to be interviewed or not being granted permission to do so prior a specified time. Their season concluding or particular legal outlines within agreements and other specific rules.
In the case of Willy Korn, he was granted permission and permitted to interview following their season in the event that he has. As would be the case similarly with other candidates. Courtesies, etc.
In addition, representatives are involved on a wide range of issues representing their clients, the coaches, and exchanges with the universities.
Things can develop quickly once the process of interviews and negotiations are underway. But discussions have limitations prior.
Interviews that can have been done, others are occurring and others could yet remain. Then once that all wraps up candidates are eventually offered next phases then initiated. ?
