Willie Pep, a defensive wizard who was arguably the best pound-for-pound pugilist in boxing history (ranked #5 on ESPN’s 50 Greatest Fighters), could bob, slip and weave past hundreds of punches per match, giving him the edge he needed to win 229 out of 241 fights from 1940-66.

Pep, aka Guglielmo Papaleo — a two-time world featherweight champion, won his first 63 bouts before losing to Sammy Angott, and then went 72-0-1 before his next loss to Sandy Saddler. No one, before or since, was that dominant — not even Pep’s modern day counterpart, the elusive Floyd Mayweather Jr.
