Nope, its also their ability to sell moves, ability to convey ring psychology, to tell a story in the ring. Their innovation both in the ring and outside, how much charisma they have in promos, interviews etc. It's their ability to both conform to the traditions of wrestling whilst at the same time being creative and different. The ability to captivate old audiences and new, to expand peoples horizons and think beyond the rediculous real/fake debate you brought up. Wrestling, when done right, is the most entertaining thing on earth...when done wrong, it is the complete opposite. Most people don't have the itnellegence or perseverence to challenge themselves to seek beyond what is force fed down their throats by the mediums they have at their initial disposal, thus the WWE-fanboy and anti-wrestling sheep, who are very similar to Rugby Union fans, in my opinion.
Their athletic ability is but a feather in a wrestling sueprstar's hat.
The f**k off and die call was thrown in there for effect, I don't actually want you to f**k off and die. My badsies.
