Earl Caddock was one of the greatest amateur wrestlers of all time as he was a three-time winner of the National AAU (Amateur Athletic Union) title before becoming a professional.  Caddock would defeat Joe Stetcher for the World Heavyweight Championship in 1917 and would later beat Wladek Zbyzsko who won a tournament for the vacant title when Caddock refused to enter it.  He never won the title back but had classic matches against Stetcher and Ed “Strangler” Lewis in title rematches.  His career was short as he retired in 1922.
