I will preface all of this by saying that much of what you suggest are good ideas. I agree with the overall assessment. They are also ideas that I believe BYU-Idaho admins have knowingly and purposefully dismissed.

The pay is (meh) okay. You will not be poor. But you also have to put up with living in Rexburg. That's not exactly a high attraction. (Sorry...........) The pay for me just wasn't there ultimately.

In my field (mathematics and statistics), the department seems to actively work to discourage research in mathematics. Any research they do is definitively in the field of math education. The whole setup is to make "college" algebra a really great experience, but at the complete compromise of the upper division courses. If you aspire to any sort of career in general academia, having a department that fights research is a little tough. Top faculty will not touch that with a 50-foot pole.

Anecdotally, I have felt that faculty at BYU-Idaho are squashed into a sort of servile "Yes sir, anything you ask sir, good sir" pattern of interacting with administration. I have spoken to colleagues who formerly taught at BYU-Idaho and strongly disliked this administrative attitude.

I get that some very good men (and women) have given up lucrative and prominent careers to come to BYU-Idaho. It's one thing to do it when you are coming in as university president in the latter end of your career. It's quite another to BUILD a career in academia at BYU-Idaho.
