Two neighbors sit at the top of Ben Roethlisberger's similarity graph separated by just 0.0001 — Ryan Shazier at 0.97 and the Pittsburgh Steelers at 0.97 — forming the two-peak structure that defines this audience's shape.

The top 10 breaks into a tight Steelers-era cluster. Six of the ten neighbors are fellow Athletes: Ryan Shazier (0.97), James Harrison (0.96), Hines Ward (0.96), Troy Polamalu (0.96), JuJu Smith-Schuster (0.92), and TJ Watt (0.92). Two neighbors are Sports Teams — the Pittsburgh Steelers (0.97) and the Pittsburgh Pirates (0.91) — and one is a Professional: Mike Tomlin (0.94). The lone non-sports entry is Sheetz (social) (0.92), a regional restaurant brand, which is the only Brands-subcategory neighbor in the top 10. The composition is almost entirely same-kind or same-franchise: athletes and teams from a single organization, with a regional brand embedded in that geography.

What the shape reveals is an audience defined by franchise loyalty rather than sport or position — the people who follow Roethlisberger follow the whole Steelers roster and the Pittsburgh sports market as a unit.
