#3 John Cena - 2013

John Cena made an incredible comeback at the 2008 Royal Rumble. Cena suffered a legitimate torn pectoral muscle while executing a hip toss on Mr. Kennedy. The injury should have required Cena to miss anywhere between six months to one full year of rehabilitation, but instead, Cena made his incredible comeback after just under four months and returned to win the Royal Rumble match.
It is quite possibly the best return from an injury of all-time and after becoming arguably WWE's best superstar of 2007, he deserved the 2008 Rumble win. What he didn't deserve or need, was winning the match again 5 years later. WWE gave us what was supposed to be a 'Once In A Lifetime' match of John Cena vs. The Rock at WrestleMania XXVIII in 2012 and that's the way it should have stayed.
With The Rock as WWE Champion, everyone knew Cena would win the match and challenge The Great One for round 2, but nobody wanted to see it. The first one was special and could have gone either way, but WrestleMania 29 was just WWE returning the favor to Cena for having The Rock go over the year before, and everyone knew it.
The Royal Rumble victory should have been given to someone from the SmackDown side, and Cena and Rock never should have come close to a second match.
