I disagree. Kingsbury is a very good coach. He took a horrible Arizona team and got them better every year except his last one that Kyler Murray missed a bunch of games. Murray had his best years with Kingsbury despite the fact that they didn't get along well. He did that coming straight from being a college coach and they have been objectively worse since he was fired. I can understand an argument that he should have become and NFL coordinator or something before being an NFL head coach, but he did WAY more with his first shot at being an HC than DA did with his and still has a more wins and higher win% than DA too.
