In theory, yes. But in actuality, most head coaches try to stay out of the way.
Especially when it's on a side of the ball where they have the least expertise. I have no doubt though that he is in full control of what we do offensively. Maybe not in play calling but in the overall scheme of things. The inner OC in him is always going to be there, just the nature of the beast when you make that kind of hire for your head coach. But as for defense, I really think he tries to be hands off because really, it makes most sense. No coordinator wants a dictator. Manny ran his own show here and Wilson has been given same free reign from what I can tell. I agree, it sounds weird that he doesn't intervene when he should but in grand scheme of things, I can see why it works best that way. To me, the best case solution with Mullen from Day 1 has always been find a top notch D coordinator and do what we can to keep him. That's the key ingredient that will make us at our most dangerous as a football team as long as Mullen's head coach because we're going to always have adequate offenses.
