Same record.
Different souls.
A team has a style. Power, speed, scoring, run prevention, strikeouts. Compare two ballclubs from different decades—first as they played, then against the league they inhabited.

Find a team's statistical soul mate.
Pick a team-season; find its nearest or most different fingerprint among other years in our current sample. Similarity is a distance measure, not a claim that two teams would be equally strong or win a hypothetical matchup.
How the similarity is calculated
For each of four positive, league-relative dimensions (scoring, power, speed, run prevention), take the natural log of Team A's index divided by Team B's index. The distance is the square root of the sum of four squared log-ratios. Lower means more similar. All four dimensions must be available and greater than zero; comparisons from the same year are excluded.
