Two things don't make sense about this whole thing. One, for a long time JJ has stated he wants his HC to be a coordinator as well, and not a "walk around head coach." So is JJ changing his stance on what his HC does? And two, didn't Gruden and Kiffin have a falling out in TB? If he's looking to possibly replace Garrett, and Gruden and Kiffin don't get along, then how would this be setting the stage for a Gruden-Kiffin reunion?
There's always more to the story.
