The past year has featured some of the best matches in John Cena's entire career, but, aside from the fantastic US Open Challenge, the booking of John Cena was a huge contribution to the disaster that has been 2015. As the year began, Rusev was an undefeated monster heel who had soundly defeated Sheamus to become the United States Champion. Like Bray Wyatt the year before, Rusev lost to John Cena at WrestleMania and then went on to lose again at Extreme Rules, and again in an "I Quit" Match at Payback. While far from being unsalvageable, Rusev has yet to recover from those three decisive defeats. Next up for the 15-time World Champ was NXT Champion Kevin Owens. Like Rusev before him, Owens secured the victory in their first PPV match but would lose the next two encounters, including another submission. Cena's next feud involved the WWE Champion Seth Rollins. Like the two heels before him, Rollins won the first encounter, a Title vs. Title match at SummerSlam. Continuing the trend of needing multiple victories before ultimately winning the feud, Cena defeated the WWE Champion cleanly in the next two PPV/Special Event matches, Night Of Champions and Live From Madison Square Garden. To summarize, John Cena successfully vanquished the undefeated United States Champion Rusev, the undefeated NXT Champion Kevin Owens, and the WWE World Heavyweight Champion Seth Rollins all within 6 months. If that doesn't provide a good illustration of why there no new stars, why no one is over (except Cena and Lesnar), and why 2015 was so poor creatively, I don't know what will.
