Why this ranking
James J Jeffries ranks #71 with a 85.89 score on the 60-100 H&G All-Time Index. His standout win in our data is over Bob Fitzsimmons in 1902, who reached a 1,674 Peak-form Elo, one of the stronger opponents on his record. He also fought Bob Fitzsimmons 2 times, going 2-0-0 across that series. The honest tension is that the sustained head-to-head rating signal is around the typical top-1000 fighter rather than an exceptional lift, so this high placement rests more on résumé signals than on peak rating level. Data Confidence is Low, so the rating should be read with wider uncertainty. Peak-form Elo is 1,795 (±235), separate from the 60-100 career Index.
