I don't believe it's wrong, but perhaps I didn't communicate my thoughts properly here. Like I said, when I refer to someone's ability as a "worker", I'm simply referring to how they are from a purely athletic standpoint. I see that the term "worker" does not only refer to how someone is athletically in the ring.
And whether you find someone's beliefs to be erroneous or not does not mean that they're irrelevant. It's simply a difference in opinion. I haven't gone here to try and tell people why they're wrong (I save that for Horatio ******io a.k.a. The Aritst Formerly Known As CmPunker), just why I disagree with them.
Entertainment is almost entirely subjective to the opinion of the individual.
Entertainment is generally subjective, but at the same time the vast majority of people recognize greatness when they see it.
When it comes to wrestling, athleticism can help you be wildly entertaining in the ring, but above all else it is character that entertains the masses. Maybe your character is extremely athletic, and the wrestler displays that through his ring psychology. Guys as great as Kurt Angle or as mediocre as Shelton Benjamin have built careers on that.
Other guys aren't blessed with the athletic prowess of a Kurt Angle, and their characters don't display that. Look at Vader, for example. He wasn't exactly about to chain wrestle across the ground, but the Vader character had little interest in engaging in that type of contest. Instead he found ways to use his imposing size to dominate his opponents, and that was his ring psychology: look like a monster, talk like a monster, act like a monster.
Look at Undertaker. He's not exactly the most athletic guy in the world, but he has one of the greatest characters in wrestling history, and he sells the crap out of it with his ring psychology. He uses dominating and humiliating moves like the chokeslam or the Tombstone Piledriver. He measures his opponents before delivering devastating strikes. Everything he does is deliberate and powerful, just like his character. He sells his match not by running around the ring pulling crazy stunts, but by using his character to sell the match.
That's what ring psychology is: not wrestling the match as an athlete, but as the character you walked down the ramp as. It's the ability to play your role when you're in the ring just as well as you play it outside of the ring. It's why if you blurred out the faces and attire and just saw two shadowy figures wrestling each other in the ring, you'd be able to identify which one is Hulk Hogan and which one is The Million Dollar man, or which one is Stone Cold Steve Austin and which one is Mick Foley.
If that doesn't enlighten you, I don't know what will.
