Notre Dame Football's nearest audiences span athletes, journalists, sports-talk personalities, and non-sports brands — with no single neighbor pulling far ahead of the rest. Similarity scores measure how closely two entities' audiences resemble each other in composition; here, the top 10 compress into a narrow 0.91–0.88 band, the hallmark of a flat shape.
Urban Meyer leads at 0.91, followed by Mike Golic (0.90) and Colin Cowherd (0.90) — a coach-turned-analyst and two sports-media figures, not fellow college football programs. Ohio State Football (0.90) and Jim Harbaugh (0.90) are the only other Sports Teams and Athletes in the top five, and both carry a distinctly Midwestern, Big Ten-adjacent footprint. The subcategory breakdown across all ten neighbors is telling: Athletes (three entries), Journalists (one), Professionals (one), Sports Teams (one), Grocery and Superstores (one), Destinations (one), Podcasts and Radio (one), and Fast Casual Dining (one). Sports-media figures — coaches, analysts, and beat reporters — dominate, but Meijer (0.88), Cedar Point (0.88), and Keyshawn, JWill & Zubin (0.88) round out the set, pointing to a Midwest-anchored, broadly sports-adjacent audience that also overlaps with regional consumer brands.
The flat shape here reflects an audience that is diffuse enough to mirror a wide range of entities simultaneously — no single neighbor commands the field.
