Mr. Kennedy is definitely the future of sports-entertainment, if you do not believe he his yet. He is charismatic like no other in the WWE at the moment and can cut awesome promos. He's definitely got the look to be a huge superstar, being cocky, funny and credible. Have you ever heard some of his promos during house shows ? I say look on YouTube and you will see that he gets huge pops.
He is still a great heel, even if he gets huge pops, but he will become an even better face. He is going in the same direction than the Rock and Austin as far as his push is concerned, but he is bigger than they were at that point of their careers.
Add that to the fact that he's an incredible athlete, who produces great all-around matches. Seriously did you see the Royal Rumble match he had this year against Batista ? If you watched the same match as I did, knowing that Batista doesn't not how to work ****, and that you saw that the match still turned out ok, you will see for sure that Mr. Kennedy is great in the ring, and is improving as we speak. He is a hard worker, and is going to be bigger than John Cena for sure, since he is a more skilled in the ring. I definitely see these two growing together in the business, with a feud somewhat apparent to the Rock / Austin feud.
Hope that's enough for you my friend. I think you can compare some of Kennedy's work with Ric Flair's in his prime (don't take this the wrong way). Some of it is similar, but I obviously know that they both are completely different.
