To me he is and has been since Survivor Series.
But they haven't really utilized his push well, or dare I say at all, since Survivor Series. Sure, he did beat Harper at TLC to regain the IC title, but that means squat, they jobbed him to BNB like two weeks prior to the Rumble.
He isn't the major title picture, they'd pretty much killed him when he lost the title to BNB and he's been jobbing to Rollins and Wyatt for a while now.
My guess is that they'll have him do something irrelevant at Mania which sucks, and then who knows, perhaps MITB 2015 could be his salvation.
