I think John Cena needs to be built up more before the Rumble. He needs to be taken as a serious contender in the Rumble match.
His position as face of the WWE for the past 7-8 years and 12 world titles are not enough. He needs to squash Dolph Ziggler one more time to really put him over.
He should kick out of 12 zigzags for every World title he has held and 10 superkicks for every year he has been in the company. Then 5 moves of doom and GTFO.
