The top 10 neighbors for Kirk Herbstreit form a tight, homogeneous cluster — TV personalities, college football media properties, and sports journalists with no meaningful gaps between them. Similarity here measures how closely two entities' audiences resemble each other in composition; scores across the top 10 span only from 0.98 down to 0.94, a narrow band that defines the flat shape.

Rece Davis (0.98) and Chris Fowler (0.98) sit at the top, both fellow TV Personalities — the subcategory Herbstreit himself occupies. College GameDay (0.96), a TV Show, follows immediately, with Danny Kanell (0.96, Athletes) and Clay Travis (0.95, Journalists) rounding out the top five. Sam Ponder (0.95, TV Personalities), FootballScoop Staff (0.95, Websites), Desmond Howard (0.95, Athletes), College Football Talk (0.94, Websites), and Marty Smith (0.94, Journalists) complete the set.

Tallying subcategories across the 10: three are TV Personalities, three are Journalists, two are Athletes, and two are Websites — all orbiting college football media. The top 10 contains no entities from outside that ecosystem; every neighbor is either a broadcaster, a reporter, a former player turned analyst, or a college football content property.

The flat shape reflects an audience that is deeply sport-specific and media-native, with no single neighbor pulling away from the pack.
