There always seems to be stories about WWE/Vince wanting to create new stars, but they never follow through with any of it. It seems like they'll push guys to mid-card level, i.e. Miz, Morrison, MVP, Kofi but they are very reluctant to let those guys get to the top of the pile with Orton/Cena/HHH/Michaels. I know that Legacy are getting a lot of exposure recently, but as soon as they split them up, those guys will fall away again and we'll still be left with the same guys doing the same matches.
It'd be so easy to do something like a 'Chance of a Lifetime' story, where four mid-card guys get to battle it out to get a title shot, leading to a new feud, and maybe get that guy over as a main-eventer. But some ego's would have to take a little bruising for that to happen...
