The most well-known wrestler ever is Hulk Hogan, and he gained his fame through charisma and bulk. The guy was huge and yet not a scientific wrestler by any means. With the Hulkster, power trumped everything—until he got old.
The wrestlers here are generally not large, but they made their way through the game by showing an interest and aptitude for the sport behind pro wrestling. Wrestling was probably the first-ever sport thanks to Cain and Abel, so there is a great history of man perfecting wrestling technique.
The 30 greatest technical wrestlers ever put time in the gym, not just to bulk up but to refine their game, and here we recognize them.
P.S.: I did not include Asian wrestlers because they would probably take over the list, and I do not know enough of them to judge fairly.
