sorry dont buy it at all dex.
firstly SRR was a middleweight and therefore a bigger man, secondly he was tough as they come and would have beat floyd badly at times, yes SRR lost but he also won many many more... i personally think he lost those bouts due having off nights.
a little bit of info for you:
Robinson was 85–0 as an amateur with 69 of those victories coming by way of knockout, 40 in the first round. He turned professional in 1940 at the age of 19 and by 1951 had a professional record of 128–1–2 with 84 knockouts. Robinson held the world welterweight title from 1946 to 1951, and won the world middleweight title in the latter year. He retired in 1952, only to come back two and a half years later and regain the middleweight title in 1955. He then became the first boxer in history to win a divisional world championship five times, a feat he accomplished by defeating Carmen Basilio in 1958 to regain the middleweight championship. Robinson was named "fighter of the year" twice: first for his performances in 1942, then nine years and over 90 fights later, for his efforts in 1951. He defeated other Hall of Fame fighters such as Jake LaMotta, Carmen Basilio, Gene Fullmer, Randy Turpin, Carl 'Bobo' Olson, Henry Armstrong, Rocky Graziano and Kid Gavilan. Robinson engaged in 200 pro bouts, and his professional career lasted nearly 26 years.
