I never thought I'd be saying this but JOHN CENA!
Cena taking the title from CM Punk would do the following:
1) Be a great match. Punk always gets the best out of Cena.
2) Be a potential ratings boost thanks to all the returning casuals who lose to see their champ.
3) Piss off the the IWC meaning we'd all be rooting for the next contender.
4) Position great heels like Barrett, Ziggler, Bryan*, Rhodes, Sandow, Orton* to take it off him. *subject to a quick heel turn
5) Set up a possible Ryback heel turn!?!
If Cena were to win tonight it would make a lot of sense. Let him have the strap for a month then drop it to one of the above at TLC.
