I guess you misunderstood Rock. He meant what Cena did in the past year that changed something and probably trend on Twitter. I was immediately thinking about hoeski and Wendy to a lesser degree. He was not burying the whole last year.
Also, extremely funny to me was the heated promo between Jericho and Punk about who was the best in the world for who to come out. Daniel Bryan. The real best in the world. Ahahah that was a good moment.
He was having a dig at Cena, which annoyed me since Cena has had a good year I feel. Although the whole segment was like a level from DigDug. So many little digs! @_@
