"Cena sucks!" For nearly a decade, John Cena has endured those chants from fans across the globe as he stepped into arenas to do battle with some of the most despicable villains in WWE history. And every night, he has hustled to prove his detractors wrong, turning in outstanding, inspired performances in some of the most monumental and epic contests of this generation. He has squared off with The Rock in the biggest pay-per-view draw of all-time, made a star of Daniel Bryan at SummerSlam in 2013 and wrestled a series of classic matches with CM Punk. He has gotten terrific bouts out of a plethora of different stars, including the lumbering Great Khali, the explosive Umaga and the brawling Texan JBL. Yet, for some reason, fans still shower him with chants of "Cena sucks." Those fans point toward what they perceive to be a lack of wrestling ability on Cena's part, despite the fact that, as stated above, he has been one-half of some of the greatest matches of this generation. Sure, the leader of the so-called Cenation is never going to be a guy that throws a tiger suplex with regularity, nor is he going to break out thirty variations of an arm bar, but Cena understands crowd psychology and is a master of the babyface comeback. Still, that does not stop the haters. And Cena has not always done an excellent job of backing himself up. While he is fairly consistent, there have been a few instances in which the fans' judgments of him have been justified. What were those moments? Why did they make the cut? You can't see him but you can see these eight times Cena actually did suck.
