Eight of Michael Irvin's ten nearest neighbors are fellow athletes, and the top four — Emmitt Smith (0.97), Dez Bryant (0.96), DeMarco Murray (0.93), and DeMarcus Ware (0.93) — form a tight band that separates clearly from the rest of the set. That gap between the top cluster and the remaining six neighbors is the structural story the two-peak shape captures.
The top cluster is almost entirely Cowboys-connected athletes: Emmitt Smith and Troy Aikman are fellow members of the 1990s dynasty; Dez Bryant, DeMarco Murray, DeMarcus Ware, Dak Prescott, and Cole Beasley are more recent Cowboys players. Deandre Hopkins (0.90) is the one athlete in the top 10 without a Cowboys affiliation by subcategory alone. The second peak of the shape is the Cowboys franchise itself — Dallas Cowboys (0.89) and Blogging The Boys (0.87), a Cowboys-focused blog — which anchors the organizational side of the same audience. Troy Aikman (0.86) and Cole Beasley (0.86) round out the ten, keeping the set almost entirely within one franchise's orbit. No non-sports entities appear anywhere in the top 10.
The shape reveals an audience defined tightly by a single franchise ecosystem rather than by football fandom broadly.
