Good question 😀!! I'm serious on the content, just because a coach is successful at one level doesn't mean he will be successful at a different level. In most cases it is when a coach goes up in level (Saban, Holtz, Rhule, Spurrier, Moller, Callahan and many more) that they are not as successful as they were before. Not sure when a coach drops a level especially from college to high school, I don't recall any. So Saban to Edinburgh sounds great, he may or may not make a difference I guess ??
