As soon as WWE launched a new 'x15' John Cena t-shirt last week, it pretty much gave away that he'd be losing at SummerSlam. Surely WWE wouldn't have released such a shirt if he was going to beat Seth Rollins and become a sixteen time champion just a week later? As a consequence of the new shirt, a Cena win is going to be quite the shock this weekend. To be honest, no matter when it happens, it is always going to be a bit of a shock to realise that he's matched Ric Flair's sixteen championships. His career is very close to being considered WWE's most successful run ever, with over ten years of main event matches and championship achievements.
