I disagree with the huge payday for Willard. Recruiting has traditionally been at least 50% of the driver in a program's success, but in a world where recruiting is not nearly as important as it was even 5 years ago, and most major programs have GMs, the coach's role is changing, and is less important than it was 5 or 10 years ago. In fact, I think college coaches have become much more disposable than they were before, similar to NBA Head Coaches, and I would not pay them the huge salaries they have historically earned.
A program needs a coach for player development, game planning, and game coaching. Coaches are not selling players on coming anymore, the NIL deal is doing the selling. The AD and GM are arranging that money, so they don't need to pay the coach for the roster anymore, which is a big part of what the coaches were getting paid for in the past. And with 50% of rosters leaving every year anyway, why pay a coach that isn't getting it done just to keep the roster together? Coaches have become a lot less valuable in the NIL and Transfer Portal era.
