Why this ranking
Billy Conn ranks #52 with a 87.85 score on the 60-100 H&G All-Time Index. His standout win in our data is over Young Corbett III in 1937, who reached a 1,932 Peak-form Elo, one of the stronger opponents on his record. In one case a result was later reversed: he beat Teddy Yarosz once, then lost to him in a later fight. Data Confidence is Medium, so the rating should be read with wider uncertainty. Peak-form Elo is 1,961 (±190), separate from the 60-100 career Index.

About this rating
Rankings: H&G All-Time Index v2.0.0. Reflects fights up to , the most recent on record. The ratings are fixed to that point, so fights after it are not yet included.
The rating itself is built from the 62 bouts we hold full data for from 1934 to 1948, which is why this count differs from the professional record above.
For the data-minded
Peak-form Elo rating: 1,961 (peak dated 1940-09-01). This best-point rating sits on its own scale and is not directly comparable with the 0-100 index.
The peak estimate carries an uncertainty band of about ±190 Elo, so read close comparisons with care.
