So, it's a time honored tradition because every guy who has one (mostly heels) chosen the moment when the Champion is weakest to cash it in? Like, they're supposed to "backstab" the Champion. I don't know how Cena's actions in this are in any doubt. DBD was quite clear after he won it that it was a 'tainted victory' and an 'easy way out' to prey upon the weakened Champion. Course he also declared that 'real men have beards' so, take that for what it's worth. The point is: for years now Cena has been presented as the boy scout who will never so much as bend the rules as it's below him (and the WWE UniverseTM) to do so.
