Gable could very easily be considered the GOAT. Flo seemed to lean very heavy on longevity. Guys like Smith, Burroughs, Baumgartner, who are all also very worthy of being in the conversation, Ranked higher due to this. As was pointed out by the OP, when it comes to complete domination, Gable stands out.
Just like an OW award, I think you need to set the standards that you use to make your picks. For example, at a tournament is the OW the most dominate Wrestler who pins everyone? Is it the Wrestler who goes through the toughest weight class? Or is is a Wrestler who comes out of nowhere to win? All could be the right choice.
What also gets lost here is the old time wrestlers. Wrestlers from a ways back who do not get the recognition they should. For example ROBIN REED, who I would bet most Wrestling fans never heard of! If I was to create a movie of what he did, no one would believe it to be possible!!!
I guess he is considered the GOAT before WWII, but does not get greater consideration because "that was way back before....." I would always say when someone says "well today the athletes are better, stronger, faster, better trained" all which may be true? But how come no one else was doing it? How come some one like Babe Ruth was hitting more HR then entire teams???
Also these athletes had the same training and techniques of the eras that they competed? Dan Hodge destroyed everyone in his path during his college career, why was he able to be so dominate? Maybe you can point to varies reasons, Hodge had unreal grip strength, Gable Trained like a madman ..... But they only could face the competition in front of them at the time, and they did so better then any others!!!
The folks of IOWA should also be talking about Farmer Burns and Frank Gotch. 2 more Wrestlers with unbelievable achievements!
