I'm a Michigan fan so no dog in this fight. I'm also a retired college professor with a PhD. As far as using Doctor as a form of address, outside of academia, I almost never use it. The ones who insist on using it outside of academia are mostly asshats who are full of themselves.
This former Minnesota faculty member who is pushing the nonsense about Fleck, strikes me as a loser whose greatest skill is the art of inflated self promotion.
He does have a PhD, but his highest career level was adjunct faculty, the lowest echelon of faculty. Adjuncts are part timers who generally sign contracts semester to semester, get no benefits, and can have their contracts not renewed for any or no reason at all. The next step up is full time instructor, then assistant, associate, and full professor.
There are plenty of PhDs who are unable to make careers in academia, but for someone who is committed, spending multiple years as an adjunct often means there are shortcomings preventing professional advancement.
Dr. Asshat makes a big deal about being "demoted" by UM as a form of punishment. It's not possible to be demoted from the lowest rung of the ladder. He quit because of his supposed demotion and did not want to fight the "demotion." The only thing that makes sense is something else he brags about: coordinating some some sort of freshman orientation program. The fact that they let an adjunct do this tells you much of what you need to know. At the schools I've taught at, which range from community college (yes, as an adjunct) to a private college to a large state university, overseeing freshman orientation was never seen as a plum job that people sought out.
Apparently he was promised this freshman orientation position for 3 years (and duties for this would not have been a year round or full-time position). It's obvious the university investigated the accusations he made, and like anybody with a lick of common sense would discover, the allegations were taken out of context and manipulated all with the aim of putting Fleck in a negative light, never mind that there wasn't much there at all. With his exaggerated and spiteful claims, It's no wonder Dr. Asshat was not continued in that position.
Now Dr. Asshat is trying to position himself as some sort of voice for student athletes victimized by coaches and college administrators. Given what he has provided so far, student athletes (and everybody else) should realize he will twist and take out of context the words of student athletes to promote himself and his agenda without a care for the damage it does to not only the coaches but student athletes as well.
