I think it's unfair to say that DiBiase can't get over and I'll tell you why. He's not been given a whole hell of a lot of time to connect with the fans as a singles competitor. They started a decent program with him and Maryse, and frankly, she did everything she could to avoid making him look good along side of her. She was (understandably) looking to improve her own stock.
Then he disappeared shortly after their breakup. When he came back, he started to work with Cody and had a great turn as a face, but it was a bit too soon, and then poof, that was it. Bye Ted, thanks for coming.
A guy cannot get over (Zack Ryder not withstanding) unless he's given some time to connect with the audience at large. I feel the same way towards Daniel Bryan's character. He's Mr. Money In The Bank and where the hell as he been? Anyone even remember him? And I mean people who aren't aware of his previous accomplishments. For many of the audience, they're first taste of him was NXT/Smackdown. And he's failed to really connect and get noticed by the majority of fans.
I can throw a few other talents in there: Ezekiel Jackson, Justin Gabriel, Tyson Kidd, Tyler Rex, Johnny Curtis (WTF is going on there?), Alex Riley, Curt Hawkins, Brodus Clay, The Uso's, Jinder Mahal, Drew McIntyre, and so on. All of these people have been given mini-pushes at some point. They were referred to in promos, in story lines, etc, just to disappear from existence with no explanation and certainly no mention of them on TV. Poof, gone.
It's really hard to prove yourself worthy of more when you're given next to nothing to begin with. Sheamus looked like shit when he debuted, but they stayed behind him and gave him room to grow, and look where he is now. It's not that hard to build a talent if you actually remove some of the established guys from the script. You don't need 50% top names on TV at all time.
Ted is talented in the ring, he needs help to get over outside the ring and that's only going to happen when he's given a little room to grow. For chrissakes, they're still shoving Ziggler and Swagger down our throats....to very little reaction by and large. They're talented in the ring, and I think with more time in a legitimate storyline, they'll get the reaction they need to take it up to the top levels. Not "face of the company" but definitely top tier. Same goes for Ted.
