Cena even flat-out said "I don't respect The Rock" and spent weeks trying to pry "the REAL Rock" out of Dwayne Johnson because for him to feel like he actually accomplished something, he had to beat peak Rock and not some pale imitation.
By the time Cena decided to go for the People's Elbow, he totally felt like he had been largely dominating the match and that this was not peak Rock and felt like he was just gonna own this idiot for not even caring enough to "show up" for this match by beating him with his own move.
