This is a good point. What's ironic is that American Football playbooks, formations, and strategies are almost ludicrously complex. And the number of people that think athletes are "stupid" is amusingly large. A large number of the latter are ignorant of the former, including a large chunk of "intellectuals" contributing to closed access journals. people are intelligent in various ways, 3D spatial intelligence for example does not translate into wirting per-se. Nor does it follow that because you are book-smart you will have a clue about analyzing game film.
