Why Chang Jung-koo ranks #58 in Boxing
Chang Jung-koo ranks 58th among Boxing athletes on GOAT Rank and 502nd of 4013 across every sport in the index. The published GOAT Score of 87.8 is the weighted result of five verified category scores: Dominance 88, Peak 94, Longevity 78, Honours 88, Statistics 92. Those categories are normalised against the full Boxing reference universe of 231 records, not a shortlist, so the position reflects the whole sport rather than a handful of famous names.
The record covers 1980–1991 with 12 documented competitive seasons. The strongest single season in that series is 1986, which sets the Peak component at 94. Peak is the defining strength of the profile at 94 out of 100, and it carries 20% of the final score. The underlying career record includes title defences 15, career wins 38, knockouts 17, world title reigns 2.
Immediately ahead sits Humberto González on 87.8, a gap of 0.0 points. Directly behind is Georges Carpentier on 87.7. The position moves whenever the verified record moves: new titles, new seasons or a corrected source all feed straight back into the same formula, and every change is dated on this profile.
