Cross-Sport · Era-Adjusted
Rankings as of 2026-07-24, as declared by the corpus that produced them.
Every sport now has an era-translated single-season board — “what would this year look like today?” Put them on one shelf and a question follows: whose season stood the furthest above everyone around them? We rank by z — robust standard deviations above the player's own era's positional peers — the one dominance measure that means the same thing whether you played forward in 1996 or running back in 1990.
Each season is z-scored against its own (season, position-group) peer distribution (robust: median & IQR, so outliers don't inflate the bucket) and re-projected onto the group's most-recent rated season. The translated value is within-sport currency and is never compared across sports; only the z is. Thin peer buckets are floored out so an early, sparsely-populated season can never mint a fabricated cross-sport rank. One honest caveat: z is normalized withineach sport's positional peer groups, and sports with finer position granularity (the NFL especially) tend to produce sharper z-tails — so the very top skews toward football. z is the most comparable axis that exists across sports, not a claim that one sport's ceiling is objectively higher. NFL rides the z-native dominance board (the second lens on the NFL era-adjusted page — distinct from its per-game “2024 terms” board); NBA, NHL, and MLB ride theirs. MLS is absent — its value model isn't VAL-based, so there is no honest z to place it on this axis.
Use the decade and position lenses below to ask sharper questions — the greatest 1990s season across sports, or the most dominant running-back / forward year ever. The Dominance Twins re-pair within the decade you pick.
Showing 50 of 250 seasons. Ranked by z— robust standard deviations above the player's own era's positional peers. The translated value (→) is that standing re-expressed in the sport's modern currency and is within-sport only; z is the one axis comparable across sports.
Seasons that stood equally far above their own eras — near-identical z, different games. The shared z-axis makes the comparison honest: this is what “equally dominant across sports” actually looks like.
