Cross-Sport · Career Twins
Two men, two different games, two different centuries — and almost exactly the same answer to the only question that transfers across sports: how far above the people you actually played against did you stay, for how long? These pairs finished level on careerZ. The curves show they did not get there the same way.
A pairing is never within one sport — the whole claim is cross-sport — and each career appears at most once, with the strongest anchoring first. The curves are aligned by career year, not calendar year: twins are almost never contemporaries, so plotting real dates would put them in different halves of the chart and compare nothing. Each man's actual span is printed beside his name. Zero on the chart is the era median — the reason a long average career accumulates nothing — and a missing point is a season too thinly-peered to measure, not a zero.
