mrbooker,

You are obviously a John Cena fan who truely believes that Wade Barrett fired him.
Personally, I'm a huge fan of Barrett. Think he's the best heel WWE have had for a long time, since a young pre-dx Triple H actually. Why is he a great heel? Because, besides being able to play the snobby superior character extremely, he can work the crowd. He can make them give a damn about him and that's the sign of a true superstar. You could have the best in-ring skills, but if you can't make the fans care about you, then you can only get so far.
In regards to what you actually originally posted about but then got completely side tracked as it went on, I understand what you're saying. After this feud, will Barrett still draw as much as he is at the moment. The answer is; we'll have to wait and see. The next feud after he's finished with Cena will tell us a lot about that. If rumours about it being him against The Undertaker at Wrestlemania are true, then he's going to be here to stay for a long time, so you're going to have to get used to it.
With the gibberish spiel that you went off on as you lost what the concept of your original post was about, there would be no wrestler, including you're beloved Cena, that would be over if somebody hadn't given him the rub. Austin was brought up and you dismissed it...why? Somebody used McMahon as the guy that put him over and you said he was already getting cheers before that so it doesn't count. Ok, what about Austin and Bret Hart? Bret Hart made Austin over in the first place by entering in a feud with a relatively unknown mid-carder and making him one of WWF's biggest stars in the process, I would say as big as Cena is now, before McMahon elevated him to a level reached by very few others. (Hogan, Rock....)
Undertaker was put over by Hogan. Yes, he lost the title straight away after but he was still put over by Hogan which helped build his legacy. Kane, who you also dismissed because he was written into a storyline which put him over..............WTF do you think is being done with Barrett, Nexus and Cena?!?! It's all part of a story line. The exact thing that you dismissed the counter argument of Kane for can be said for Barrett. Brock Lesnar beat The Great One, The Rock on one of the biggest Pay Per Views of the year. Brock Lesnar was catapulted to main event status just as fast as Barrett was. The list is endless.
This is how the wrestling industry works. To make a star, you have to make the audience care about the individual and with Barrett, it's clearly working. Look, you cared enough to start this thread about him and you've got 5 pages of replies about him. We care about him, love him or loathe him, he is relevant. Will he be relevant in his next feud and years after this one, maybe, maybe not, but this is how household names are created so you need to come to terms with the fact that Barrett is around, maybe to stay, and that John Cena isn't really fired!!!
