Anything else that coaches want to accomplish in their careers is greatly enhanced by winning. Culture, destination jobs, etc., are all okay as long as your staff understands how to get there. At least, the newly hired coaches seem to understand this. It's not as important how long they stay, as it is what they do. For proof of this, just look at the most successful program.
We have had a lot of investment in graduating players. The NIL and transfer portal situation, caused by the NCAA itself, has made this obsolete for the non-factory programs. The NCAA has pushed progress toward graduation, instead of actual graduation. The NCAA on-field rules changes have even favored forcing schools to go to NFL schemes. Bottom line, the NCAA has forced their members into minor league football. The model of one-year scholarships, and a high turnover of ambitious assistants is the one that the NCAA favors. That is the reason that it works.
The total person concept, and the get old, stay old concept, have to take into account the instability that the NCAA has forced onto it's members. You can do anything you want, as long as you understand that it's one year at a time. Loyalty has been made an unaffordable luxury by the NCAA.
So, if anyone is upset that fans are ready to flush both coaches and players, then they need to take it up with the root cause, the college presidents. They created the environment. Pardon the people who donate heavily. Pardon the people who buy tickets Pardon the people who foot the bills if they want to participate in the fun.
This forum is often criticized for its volatile rhetoric. Welcome to the world that has been transitioned to by the NCAA. Gentlemen, start your engines.
