What happened to John McClain?

First of all, let me emphasize that I do not give a single s**t about John McClain’s opinions. But I am genuinely curious on what has caused him to hate the Texans now. He used to be a normal reporter, now all this guy does talk s**t about his own team and I’m wondering why; especially since we actually have some happiness now. Was he an Easterby truther? Beef with Hannah? Is he just an old ass man? What happened to him?
