The problem with the Briles situation is there is so much more opinion out there than fact. It's hard to win that PR battle even if the guy was simply scapegoated.
Personally, I'm a believer in second chances and innocent until proven guilty, so unless there is evidence he covered up a crime I can't have strong feelings one way or another. A football coach is not the one admitting students to the school nor should he be expected to actively police the personal lives of 85 young adults.
Considering his age and that any other interested program would also be facing the same PR nightmare, I think his stock as a head coaching candidate is actually pretty low. If he badly wants to get back into coaching I wonder if he would take a position as an assistant/advisor if someone hired his son Kendal as head coach. Kendall alone is probably too inexperienced to be a top candidate, but with a few years of daddy's coaching guidance..
