CFB is one of the most crooked, amoral sports there is. Most programs don't care if a guy has been caught cheating, has a bad attitude, or runs a dirty program if he wins. Mike Leach was a coach with a poor reputation who got fired from TT for locking a kid in an equipment closet. 3 years later he was the HC at another P5. Then he ended up back in the SEC making 5 million per year. This is a weird dude who fights with ADs and is a polarizing right wing figure, yet he had no problem getting two P5 jobs in a row.
Bobby Petrino is one of the biggest scumbags, got busted at Arkansas, two years later he was back in CFB as HC at WKU, then back to the P5 for four years, and after getting fired AGAIN he was a D1 HC within two years.
If a school thinks a coach can win football games, he'll find a job. They don't give a **** about the court of public opinion since winning fixes everything. Notice how Hugh Freeze's stock suddenly rose after putting Liberty football on the map? The fact that it took 7 years for Davis to land a job at FIU tells you what the market thought of his abilities. Yet we have deranged fans who think the market was wrong. Given that all signs point to Davis's career at FIU ending soon on a depressing note, it turns out the ADs across the country accurately assessed whether Davis had any fuel left in the tank.
