4. Sheamus
The Celtic Warrior has not been seen on WWE programming since exiting the company last year with an injury. In all that time, WWE has rarely talked about him and for the most part he is off the radar of fans. But the Royal Rumble could bring him back with a vengeance. Sheamus is one of the hardest hitting brawlers that WWE has ever known, a guy that loves to fight and never backs down despite the opponent he's facing. He has never taken a step back when it comes to a challenge and a ring full of WWE Superstars that all want to eliminate him would be no different. Sheamus is no stranger to the Rumble match of course, as he won the event in 2012. So he has a definite track record there. But the question is if he does return, does he have a shot at leaving with the win?
