Boxing P4P GOAT is Sugar Ray Robinson and it isn't really close. Mayweather is not even part of the conversation. He fought far too few times and far too few quality opponents at the peak of their games. Harry Greb (298 fights; the #2 pound-for-pound fighter of all-time by the International Boxing Research Organization) or 'Homicide Hank' Henry Armstrong (held the featherweight, lightweight, and welterweight titles at the same time when there were eight divisions) would be far better choices for the conversation.
He turned professional in 1940 (retired in 1965) at the age of 19 and by 1951 had a professional record of 129–1–2 with 85 knockouts. From 1943 to 1951 Robinson went on a 91-fight unbeaten streak. Historian Bert Sugar ranked Robinson as the greatest fighter of all time and in 2002, Robinson was also ranked number one on The Ring magazine's list of "80 Best Fighters of the Last 80 Years". As of May 2023, BoxRec (the official record keeper of the Association of Boxing Commissions) ranks Robinson as the greatest boxer, pound-for-pound, of all time. He was named the best boxer of all time, pound for pound, by the International Boxing Research Organization (IBRO) in both of its all-time ratings, in 2006 and 2019. He would be better known to the non-hardcore boxing historians if there was more surviving footage of him in action.
