It's said that a big part of why Dolph Ziggler isn't getting pushed is one of the same reasons that Christian isn't being used - his history of injuries and concussions. It was said that WWE can't push Ziggler and trust him a top guy because he's injury prone and had a history of taking time off. This applies to a few other talents as well. There's a feeling that some talents are just "snakebit" in that regard. I for one think this is complete and total bullshit. Can't they just say they don't like him?
