From Cena's first United States Championship win at WrestleMania to his most recent Mania singles success, last year saw him defeat the previously unpinned Rusev in a true old fashioned USA vs. Russia showdown. Rusev got the big Mania entrance treatment for this, memorably coming out on a tank in one of the greatest entrances of all time. The match itself wasn't too bad, Rusev showing that he could truly hang in the big time and Cena hitting all of the spots one expects from such a seasoned performer. The issue here lies in the booking, the way both men were presented when all was said and done. Everyone and their dog knew Cena was winning. and that was where a lot of the problems lay. All it took was an accidental bump with Lana and an AA to put the previously unconquerable Bulgarian down. This match, and subsequently Rusev's entire story at this point, felt like an exercise in getting Cena over, something which would have made no sense in 2010 let alone 2015. Rusev hasn't been the same since.
