Yes, in either instance you lack experience, but as a position coach
moving to a same-side coordinator you've built up, for years, your own ideas, theories, ways to teach fundamentals, and ideals on how to do things on your side of the ball. In the vast majority of cases you've spent hundreds of nights lying in bed awake discussing with yourself, "when I run this [defense/offense]..."
I guarantee that as the OL coach, Castillo wasn't nearly as steeped in that mindset, and rather just thought he could do it pretty good, given time and players.

I don't think it's an oversimplification. I think you're looking at the wrong side of it. It should be noted that Castillo has coordinated a defense before. It was high school ball, but he did have that experience. Pederson has NONE. At any level.
