He's never been seen as a top guy by WWE unfortunately. Personally I think he's gotten very stale. Basically the same face character since 2008 when he debuted. He's changed things up a little recently but he still needs a change. I doubt he'll even make the WrestleMania card this year. He needs a heel turn desperately. He could be a potential world champion, but needs to show more variety and versatility.
I know many people think he was buried in his feud with Orton a few years ago but I don't agree. He was too new and not unique enough to fast-track to the main event. I'd love a heel turn and alignment with Punk/Heyman after Mania. Could also be a potential MITB winner this year. He and Cody should be guys that are started towards a main event push later this year.
