Team reports answer one fan base at a time. This report changes the lens: it asks which sports brands look strongest when the measurement system crosses league borders.
The hypothesis is that greatness has at least three separable components: archive mass, conversion efficiency, and attention. A franchise can win one of those categories and still lose the broader identity test.
FAST FACTS
DATASET CONTEXT
This is a curated comparative model built from public reference records rather than a proprietary win-probability system. The goal is to create a shared vocabulary that later team profiles can reference.
A front-office analyst might want causal variables: payroll, age curves, draft capital, injuries, ownership. An Artometrician starts one level higher: what does the institution look like when winning, money, attention, and pain are placed on the same page?
Reader path: if you are new to the topic, treat each chart as a guided tour of one question: who leads, how concentrated the field is, what changes over time, and where the outliers sit. If you already know the domain, use the same charts as a challenge: check whether the metric is the right proxy, whether the source omits an important population, and whether the headline survives the limitations section.
CHART 1 - DYNASTY MASS
Cross-sport comparison starts with mass. The Yankees and Canadiens look like institutions because their title archives are not normal franchise resumes; they are historical infrastructure.
This chart gives future team reports a shared scale. A fan can ask whether a club is chasing its league or chasing one of the archive monopolies.
CHART 2 - CONVERSION
Appearances measure access. Titles measure finishing. The Patriots, Spurs, Warriors, and Red Sox produced different kinds of modern dominance, but each solved the conversion problem better than its peers.
That is why a merely famous team can feel weaker than a smaller, colder machine.
CHART 3 - BRAND VERSUS OUTPUT
Value is not a scoreboard. The Cowboys, Knicks, and Yankees show that brand equity can survive long title gaps, while the Chiefs and Warriors show what happens when current winning catches the market's imagination.
From a metric standpoint, this is the first big split: market power and competitive power are related, but they are not the same variable.
CHART 4 - LEAGUE ROTATION
Leagues write different scripts. Baseball's long season and playoff volatility create a different kind of access than the NBA's star-driven tournament or the NFL's single-elimination machine.
The cultural output is visible: every league teaches fans a different theory of fairness.
CHART 5 - PAIN AND ATTENTION
The longest drought is not always the loudest drought. A small-market wait can be existential; a New York, Toronto, or Dallas wait becomes national theater.
This is why cross-report analysis matters. The number is only half the story; the attention system decides how the number feels.
CONCLUSION
The cleanest finding is that sports greatness is not one ranking. The Yankees and Canadiens own archive mass; the Patriots and Warriors define recent conversion; the Cowboys own the contradiction between brand and output.
Future reports can now point back to this index whenever a single-team story needs a cross-league benchmark.

EDITOR'S NOTE
Figures use rounded public-reference values and editorial indices for attention. The report is intended as a comparative map, not a betting model.
