Len Wickwar had fought almost 4000 rounds going by boxrec. Johnny Dundee, Jack Britton and Billy Bird followed with 3200+, 3100+ and 3000+ respectively. Pep only had about 2000 or less.
Long time living myth, repeated everywhere... 1. Emille Griffith - 339 2. Abe Attel - 337 3. Hilario Zapata - 303 4. Julio Cesar Chavez 301 5. Sugar Ray Robinson - 288 They author of that list, obviously, never heard of Jack Britton, who fought about 50 championship rounds more than Griffith, over 390.
