The Rock never made another appearance during the storyline, and Cena turned babyface again ahead of SummerSlam. Speaking on Sportskeeda Wrestling's BroDown show, Russo suggested that Cena's heel turn was a monumental failure."I'm begging you to challenge me. Cena's heel turn had to be one of, if not the biggest, epic failure in the history of the business. There have been swings and misses, and that's gonna happen. But for a guy like Cena on a spot like this on a farewell tour, I cannot think of anything else that was a bigger flop than this," said Russo.
