The UCF fan base is as “new money” as they come. If Scott Frost had come back and not repeated as an undefeated “champion” then they would want him gone too. They are an upstart fan base that knows very little about football. In short, I put little stock in their complaints about Heupel.
He could still suck, that’s totally possible.
Also, neither Kiffin nor Chadwell had any serious NCAA violations tied to them at any point. Don’t call people out when you are just parroting things you’ve heard online but not read for yourself.
