At 0.98, Jay Bilas and Joe Lunardi form a near-tied dual peak at the top of Andy Katz's similarity graph — two distinct audience neighborhoods pulling almost equally, which is the defining structural feature here.

The shape is two-peak. Jay Bilas (0.98) and Joe Lunardi (0.98) sit essentially level, followed closely by Seth Davis (0.97) and Doug Gottlieb (0.95). Tallying the top 10 by subcategory: five are Journalists (Jay Bilas, Seth Davis, Jeff Goodman, Scott Van Pelt, Pat Forde), one is a Professional (Joe Lunardi), two are TV Personalities (Doug Gottlieb, Jon Rothstein — wait: Rothstein's subcategory is Journalists), and the remaining entries are CBS Sports CBB (TV Channels) and ESPN Stats & Info (Sports brand). Correcting the tally: six Journalists, one Professional, one TV Personality, one TV Channel, one Sports brand. The Journalist cluster dominates, but Lunardi — classified as a Professional rather than a Journalist — represents a distinct audience neighborhood, likely anchored in bracket-analytics followers rather than general college basketball media consumers. That split between the broader sports-journalism audience and the more specialized bracketology audience is what the two-peak shape captures. The presence of CBS Sports CBB (0.94) and ESPN Stats & Info (0.93) as institutional accounts, rather than individual voices, reinforces that the audience overlaps with college basketball infrastructure broadly, not just individual personalities.

The overall picture is a tightly defined college basketball media audience that bridges general sports journalism and tournament-specific analysis.
