Zach Johnson's top 10 nearest neighbors are a nearly pure golf ecosystem — tour players, equipment brands, and the sport's governing bodies, with scores compressed into a tight band from 0.91 to 0.94.
The shape is flat: no single neighbor pulls away from the pack. TaylorMade Golf leads at 0.94, followed closely by fellow Athletes Rickie Fowler (0.93) and Dustin Johnson (0.93), then PGA Tour (0.92) and PING GOLF (0.92). Titleist (0.92), Brooks Koepka (0.92), Phil Mickelson (0.92), Jordan Spieth (0.91), and FootJoy (0.91) round out the ten. Six of the ten neighbors are fellow Athletes; the remaining four are Brands (Fitness, Outdoors, Footwear) and one Sports League. No media channels, comedians, or TV personalities appear in the top 10 — those categories emerge only further out in the wider neighbor set.
The subcategory mix — Athletes and golf-specific equipment brands — describes an audience defined almost entirely by the sport itself, with no meaningful cross-kind signal at the top of the distribution.
