Not just one of John Cena's WTF moments, but one of the biggest WTF moments in WWE history... Brock Lesnar absolutely squashed the franchise star at SummerSlam 2014. It was like nothing ever seen before, in terms of a franchise star being demolished. Lesnar just smashed through Cena, with sixteen suplexes, before finishing with an F5 to take the WWE Championship. Can you imagine a Hogan or an Austin ever allowing themselves to be defeated like that? It demonstrated a remarkable self assuredness on Cena's part. He knew that far from damaging his reputation, such a performance would only elevate the respect people had for him.
