Southpaws are hugely overrepresented as victors against top heavyweights

- One of Holyfield's five losses in his 30's was to southpaw Moorer - One of Vitali's two losses was to southpaw Byrd - One of Wlad's four losses in his 20's and 30's was to southpaw Sanders - Two of Joshua's three losses have come against southpaw Usyk 5/14 or 36%: southpaws have beaten these top heavyweights at 2-3 times the rate of orthodox fighters. - Even in defeat, southpaws are often among the most competitive and dangerous opponents: Thompson vs Wlad 1, Ortiz vs Wilder 1, Wallin vs Fury. Furthermore, Wlad, Wilder and Fury all had a lot of southpaw experience - Holmes, Tyson, Bowe and Lewis never fought a southpaw of note as pros - Holmes was KO’d twice by a 5’10, 205 lbs, future journeyman southpaw as an amateur - At least 2/8 of Ali’s amateur losses came against southpaws and he had one of his most competitive pre-Frazier fights against Mildenberger: a 6’1.5, 195 lbs southpaw Euro champ with mediocre amateur pedigree, a suspect chin and relatively little power - Joe Louis admitted to ducking southpaws: “I don’t want absolutely nothing whatsoever to do with no southpaws. Bettina is out.” Southpaw heavyweights barely existed prior to the 90's due to American trainers generally converting southpaws to orthodox, nobody wanted to fight them (hence most historical heavyweights and trainers were untested against them and prior to Holyfield, never encountered a champion level 175+ lbs southpaw), there wasn’t a southpaw heavyweight title challenger until 1966 (European champion Mildenberger), a southpaw heavyweight titlist until 1994 (former LHW titlist Moorer) and the two most accomplished southpaw heavyweights prior to Usyk were former sub-cruisers.
