This isn't trying to reproduce who's actually in Cooperstown — it's this
project's own answer to who belongs. No linear-weight run values, no replacement-level
constant: every player is scored against the league he actually played in, season by
season and tilted toward his own position, using five genuinely separate skills — batting
average, isolated power, walk rate, stolen-base rate, and fielding.

This is a living ranking, not a set of plaques. It's rebuilt from scratch every year
on the latest data, so a player climbs onto the list when his case passes the 300th, and a
borderline name drops off when someone else's rises past him. Active players are in — no
five-year wait. What you're looking at is the 2025 edition; the twenty names just
outside the cut are listed at the bottom.
What's a Stat Above Average? Each player-season is compared to its own season — a 1927
season is judged against 1927, a 2024 season against 2024, nothing crosses eras. The five inputs
above are each converted to a z-score (standard deviations above or below the bar for that year,
computed from qualifying hitters only) and blended into one number for the season: batting
average and isolated power at 30% each, defense at 20%, walk rate and stolen-base
rate at 10% each. (Walks and steals are both dialed back — a walks-only bat or a pure
basestealer could each otherwise ride one category onto the list ahead of a complete hitter;
leaning the score on contact and power pulls the list closer to the actual Hall of Fame.) The
defensive input is Baseball-Reference's Fielding Runs for the season — the one number here that
isn't a plain box-score rate, because fielding doesn't have one.
The bar leans toward your position. A .290 shortstop and a .290 first baseman are not
the same player, but scored against the whole league they look identical — and that quietly
buried the great up-the-middle names (Ripken, Larkin, Bench) far below where they belong. So
the four bat-and-legs categories are measured against a bar set 60% of the way from the
league average toward the average for the player's own position that season. Fielding Runs are
position-relative by nature — a shortstop's are already measured only against other shortstops.
The career number blends length and peak. A player's season scores, each scaled to a
600-PA workload, are summed into a career total — with below-average seasons counted at
40% weight, so a few years too long in the league dings a great career without erasing
it. A great career cut short shouldn't be buried under compilers either, so the ranking metric
is the average of that career total and the sum of the player's best seven seasons (the
same career-plus-peak shape JAWS uses). Play a long time and at a high level and both
halves are large.
Negro Leagues players qualify on a separate standard, not the 5,000 PA floor — their
official league schedules were far shorter than MLB's, and the surviving record undercounts
them further still. They qualify instead by accumulating the equivalent of 9 seasons at
their own league's typical season size — the standard that gets Josh Gibson, Willie Wells,
and Turkey Stearnes onto this list. The NeL flag beside a player's rank marks the
ones whose score actually draws on Negro Leagues play — a 200-plus-PA season in a Negro
Major League — not a brief cameo like Willie Mays's 13 games in 1948.
Runs scored and RBI were deliberately left out — both depend heavily on who's on base ahead
of you and where you hit in the order, not just your own output. The HOF column marks
players the writers and veterans committees have already voted into Cooperstown, so you can
see at a glance where this list and the official one agree and where they don't.
