#4 Longest time in the match
Traditionally, the "Iron-man" in the Rumble is a moniker given to the man who lasts the longest in the match. John Cena was the Iron-man at the 2010 Royal Rumble match when he lasted 27 minutes 11 seconds. Cena eliminated Batista in the match before being tossed over the top rope by the returning Edge. But it was Cena who lasted the longest in the rumble and therefore still ended up being the Iron-man in the contest and at Wrestlemania that year, he defeated Batista to regain the WWE Championship.
This year's Royal Rumble might prove no different as Cena could last the longest. A lot of dream confrontations are also highly expected with the likes of a returning Goldberg, Samoa Joe, Roman Reigns and Fin Balor colliding with Cena. Spending the most time in a Rumble match would be great for Cena as this would be his basis for participating in a big match at Wrestlemania 34.
