Guess I'm missing something here because all I read were the words of a guy with a tremendous amount of confidence of himself and his in-ring ability. He basically just stated that he goes out and tries to perform to the best of his ability each and every night and doesn't mind telling people when he thinks he does it better than anyone else. Hardly worthy of a burial.
Considering how much the company struggles to come up with anything relevant for him anyways, I think it was most likely a case of pushing him but quickly getting bored of him again and thus sending him back to the undercard in short order. Same thing happened in early 2013 as well after he feuded with John Cena.
