The two clearest poles in Jayson Tatum's similarity graph are Paul Pierce (0.84) and Isaiah Thomas (0.83) — both former Boston Celtics, both Athletes by subcategory — pulling well ahead of the rest of the top 10 before the scores step down to a second cluster.
That second cluster runs from Ben Simmons (0.75) and Rajon Rondo (0.74) through the Boston Celtics account (0.72), Kyrie Irving (0.71), the Detroit Pistons (0.69), Allen Iverson (0.68), Kendrick Perkins (0.68), and the Philadelphia 76ers (0.68). All ten neighbors are Athletes or Sports Teams — seven individual Athletes and three team accounts — making this an unusually same-kind top 10 with no crossover into entertainment, media, or non-basketball sports at this tier. The Sports Teams subcategory splits between two franchises directly tied to Tatum's career context: the Celtics and, via Simmons and Iverson, the 76ers orbit.
The two-peak shape reflects a real structural divide: the Pierce–Thomas pairing sits roughly 0.10 above the next tier, suggesting those two audiences overlap with Tatum's most tightly, while the broader NBA-fan cluster behind them represents a wider but still basketball-specific neighborhood.
