MMA Style? You are stretching there. And why don't you add ability to climb into the ring, ability to brush your teeth, and ability to jerk off.
I already gave in ring ability to Hart, no need to stretch it out into everything you do in the ring.
Professional wrestling is much, much more than what you can do in the ring. Its a combination of several different aspects. Consequently, the top wrestlers and those who can be considered the best, have the ability to draw.
Austin during his most popular and influential years was nothing more than a brawler in the ring and noone would ever argue that Hogan and the Rock had the best in ring ability. Yet, noone with half a brain would say Hart was better than Hogan, Austin, or the Rock. The same should go for Cena. He is one of the elite wrestlers who has the ability to make fans want to watch what he does. They go crazy when he enters the building regardless of the circumstance or who he is facing.
Hart never had the crowd in the palm of his hand, he never elicited the emotion Cena gets from the crowd. Hart will never be considered in the top echelon of wrestlers because he didn't have the mic skills, charisma, or presence to draw a crowd.
I'll give an example. You have two employees. One has all the analytical skills required to do excellent work, yet when it comes time to deliver the presentation, he fumbles through and never gets the full support of the client, customer or board. He has trouble closing the deal and creating new business for the company. Employee number two does really consistent work. It is not as advanced analytically as employee one, but it is adequate to get the job done. When it comes time for him to present, he blows the client, prosepect, board away. He always closes the deal and leaves them wanting more. Who is the better employee?
