You can put a guy over without having him win and Cena does not deserve to break the streak.
The whole point to breaking the streak is the guy who does it will be there with you for decades, bust his ass, be loyal, be a great ambassador, not fuck up in public with the ball in his hands, just like Taker.
Only Cena fits that bill and can carry that weight without hesitation. Orton can't, Punk can't, Dolph/Cody/Wade ain't proven shit to be trusted. It's Cena or perfect record that is just the reality of the situation.
It isn't something you simply can give away and get back like losing a title and then correcting it by putting it on someone else or the MITB case ... It is one and done, that is it
